Definitions
- the present invention relates to new hydroxylated polyethers having perfluorinated side groups, to their preparation and to their use for the synthesis of materials such as fluorinated polyurethanes.
- fluorine to a polymer material leads to better surface properties, improves chemical inertness and resistance to solvents and in some cases biocompatibility.
- Fluoropolymers used as coating materials have experienced significant growth in recent years. They provide exceptional properties in this area with regard to resistance to UV radiation, the lubricating power linked to a low coefficient of friction, and in relation to the decrease in surface tension: non-wettability (hydrophobia, oleophobia), 1 anti-adhesion, anti fouling ...
- fluorinated polyurethanes which have better abrasion resistance, are of particular interest; however, the synthesis of fluorinated polyurethanes has been limited by the availability of difunctional fluorinated molecules.
- the fluorinated diols sold are very limited in number: hexafluoropentane diol, tetrafluoro hydroquinone or 4.4 ′ (hexafluoro isopropylidene) diphenol.
- the surface tension and the non-wettability of fluorinated materials are not directly linked to the level of fluorine contained in the material but to the chemical structure, to the positioning of the perfluorinated groups with respect to the macromolecular chain, and to the length of the perfluorinated chain. With equivalent fluorine levels, a polymer with perfluorinated side groups will have a much lower surface tension than a polymer comprising a polyfluorinated backbone.
- the diols having perfluorinated lateral Rp links are often obtained by acid hydrolysis of fluorinated epoxides: JP patents n ° 01.305.045 and DE n ° 3.525.494.
- the alcohol functions (primary and secondary) carried by vicinal carbons exhibit differences in reactivity.
- the diols of this type described in patents JP n ° 02.258.821 and JP n ° 02.258.822 or DE n ° 3.319.368 lead to rigid urethane segments not very favorable to favor the organization of perfluorinated groups .
- macrodiols such as polyethers, comprising pendant fluorinated groups
- polyethers comprising pendant fluorinated groups
- the ⁇ ⁇ hydroxytelechelic oligomers with pendant fluorinated groups can be obtained by grafting polyfluorinated olefins onto methylenic groups of hydroxylated polyesters: EP patent No. 0.260.842; this radical grafting necessarily leads to a random distribution of the lateral fluorinated groups, and to polyfluorinated and non-perfluorinated grafts; we know that the presence of atoms of hydrogen reduces the contribution of fluorine to surface properties.
- perfluoroalkylated ⁇ ⁇ hydroxytelechelic oligomers can be obtained by polymerization of cyclic ethers such as perfluoro or polyfluoro alkyl glycidyl ethers: US Pat. No. 3,591,547; but the polymerization conditions described in this patent are such that the chemical structure of the oligomers formed cannot be controlled. Indeed, during the cationic polymerization of cyclic ethers in the presence of acid catalysts, the initiation reaction involves a nucleophilic attack of the ether monomer (a) on the monomer activated by protonation (b). The opening of the cycle leads to the formation of a tertiary oxonium (c).
- cyclic ethers such as perfluoro or polyfluoro alkyl glycidyl ethers: US Pat. No. 3,591,547; but the polymerization conditions described in this patent are such that the chemical structure of the oligomers formed cannot be controlled. Indeed, during
- the propagation reaction is carried out by successive additions of monomer molecules to the growing chain formed by the oxonium ion (see reaction scheme 1 below). This last approach is very attractive because of its evolving nature. However, the polymerization reaction is disturbed by intramolecular transfer reactions in particular, which lead to cyclic compounds with low molecular weights. The consequences of these parasitic reactions are an increase in polymolecularity and the formation of non-functional molecules.
- the inventors observed that the coupled use of a hydroxylated initiator and of particular conditions of implementation, made it possible by cationic polymerization of perfluoroalkyl oxiranes, the obtaining of linear hydroxylated polyethers with pendant Rp chains having, unlike the prior art, a perfectly known functionality and predetermined by that of the initiator.
- This process makes it possible in particular to obtain macrodiols ⁇ ⁇ with lateral perfluoroalkylated groups, the advantage of which has been shown for the production of polyurethane materials of low surface tension.
- This synthetic route also leads to other families of fluorinated polyethers, including polyfluorinated macromonomers.
- the invention relates in particular to the following four sub-families:
- R F where Rp is a perfluorinated group comprising from 1 to 12 carbon atoms.
- These difunctional oligomers can lead to fluorinated materials by polycondensation reactions and in particular to perfluoroalkylated polyurethanes.
- Rp where R-] comprises an acrylic, ethacrylic or allylic polymerizable group.
- These macromonomers can lead to fluorinated materials by radical or photochemical polymerization.
- difunctional oligomers which incorporate a non-fluorinated co onomer can have polymerizable groups capable of subsequently inducing crosslinking.
- hydroxylated perfluoroalkylated polyethers in accordance with the invention having perfluorinated side groups, are obtained by polymerization of a monomer based on perfluoroalkylated oxiranes (homopolymerization of oxiranes and, where appropriate, copolymerization with cyclic non-fluorinated ethers substituted or not ) in an inert organic solvent.

- the alcohol used can be a mono alcohol or a polyol, monomer or polymer; the acid catalyst is used in low concentration in a ratio with the hydroxylated functions preferably ranging between 2.10 -4 and 10.
- the monomer can be constituted by one or more polyfluorinated oxiranes or by a mixture of polyfluorinated oxirane / non-fluorinated cyclic ether (in particular rings with 3, 4 or 5 atoms) with a view to carrying out a ho opolyerization of Oxiranes, with if necessary copolymerization with said cyclic ethers.
- the non-fluorinated cyclic ether can be tetrahydrofuran, an oxetane such as dimethyl 3,3 oxetane or an allyl oxirane such as glycidyl allyl ether.
- the reaction medium is produced by mixing, in the solvent, the alcohol, the oxirane-based monomer in an amount at most equal to the stoichiometry relative to the hydroxylated functions of said alcohol, and the acid catalyst.
- the addition of said monomer takes place slowly and the duration of addition is in particular between 1 and 60 hours depending on the nature of the alcohol used as initiator and the degree of polymerization of the polyfluorinated polyether desired.
- the speed of addition of the monomer is advantageously chosen to be close to half the speed of consumption of perfluoroalkyl oxirane (by "close to” is meant an speed of addition deviating at most from 20% of the speed of consumption).
- the concentration of hydroxy functions present in the reaction medium remains throughout the duration of the reaction greater than the concentration of polyfluorinated oxirane, and preferably twice the latter.
- the polymerization reaction is preferably carried out in the inert organic solvent at a temperature between 20 ° C and 80 ° C.
- chlorinated hydrocarbon solvents such as CH 2 C1 2 , CHCI3, CCI4, CCI3CH3 or CH 2 C1CH 2 C1 are suitable for the reaction; they can be used as a pure product or as a mixture.
- the cationic polymerization of fluorinated oxiranes according to this process is carried out with a conversion rate greater than 95%.
- the acid catalyst used in the process of the invention is preferably a superacid catalyst having a Hammet acidity function of less than -6 (by "acid catalyst” is meant a simple compound or a mixture of compounds); it can be chosen from those known in the art, including Lewis acids and Bronsted acids, and more particularly from the following group: BF 3 [(C 2 H 5 ) 2 0], HBF4 (C 2 H 5 ) 2 0], CF3SO3H.
- Monoalcohols and polymer polyols can also be used: polyethylene glycol methyl ether, polyethylene glycol, polypropylene glycol, polytetrametylene glycol, bisphenol A ethoxylated, polybutadiene hydroxytelechelic, polyester hydroxytelechelic, polysiloxane ⁇ hydroxylated, in particular polydimethylsiloxyl hydroxyl in particular polydimethylsiloxane ⁇ ⁇ dihydroxylated, polyphenylmethylsiloxane hydroxytelechelic, ethoxylated glycerol.
- These polymers are in particular chosen from molar masses of between 250 and 3,500 g.mole -1 .

- the fluorinated polyethers according to the present invention are essentially linear and have one or more reactive hydroxyl functions at the chain ends.
- the functionality of these fluorinated polyethers is determined by the number of OH functions contained in the alcohol molecule introduced at the start of the reaction.
- the alcohol which plays the role of initiator is consumed at the very beginning of the reaction and completely integrated in the polyether chain.
- the hydroxylated functions formed at the chain end during the homopolymerization of fluorinated oxiranes are almost exclusively secondary. The degree of _
