Abstract

Catalyst residues are removed from products made by the polymerization of trioxan in the presence of an electrophilic catalyst with at least one monomer, by comminuting the polymeric product and treating it with an extraction liquid which dissolves the catalyst residues. The catalyst may be a metallic or metalloidal fluoride, chloride or bromide, e.g. boron trifluoride or trichloride stannic chloride or bromide, or ferric chloride, their complexes with water or with an organic compound in which the donor atom is oxygen or sulphur, or a non-oxidizing inorganic acid, or a halogen or an interhalogen compound, or an oxonium salt. Specified comonomers are cyclic carboxylic esters, aldehyde, styrenes, styrene derivatives, alkyl ethers and esters, compounds containing one or more isocyanate or nitrile groups. The extraction liquid may be a solvent for the catalyst residues. Specified extraction liquids are acetone, aqueous ammonia, an aqueous solution of the sodium salt of hydroxyethyl-ethylenediamine -triacetic acid, the sodium salt of diethylene-triamine peracetic acid or the sodium salt of 1 : 2-diamino-cyclohexane-tetra-acetic acid, an alkaline aqueous solution of dihydroxyethyl-glycine or its sodium salt, or an aqueous solution of triethanolamine. Specifications 557,873 and 903,668 are referred to.
