Abstract

Polyacetals comprising the recurrent group -CH2CH2OC(R)2-X-, optionally with -CH2-(CH2O)m-C(R)2-X-, wherein at least one X group is sulphur, any remaining X groups being oxygen, m is 0 or 1, R is H, alkyl or halogeno-alkyl, may be used as lubricants.ALSO:1:3-Oxathiolane is prepared by reacting mercaptoethanol with a stoichiometric amount of paraformaldehyde in the presence of an acid catalyst. The crude product was purified with KOH or Al(OH)3 and dried over metallic Na.ALSO:Sulphur containing polyacetals are prepared by polymerizing a compound of Formula (I) <FORM:1040729/C3/1> either alone or with a compound of Formula (II) <FORM:1040729/C3/2> where at least one group X is sulphur, X otherwise being oxygen, n is 0 or 1, R is a H, C1- 4 alkyl or halogeno-alkyl group, using an acid catalyst (e.g. a mineral acid or a Lewis acid or addition compound thereof) and, optionally, a chain terminator (e.g. an alcohol, amine, thio-alcohol, open-chained acetal, ester or amide). Specified monomers are ethylene, propylene and butylene oxides and sulphides, epichlorohydrin, 1 : 3-dioxolane, 2 - methyl - 1 : 3 - dioxolane, 1 : 3 - oxa - thiolane and 2 - methyl - 1 : 3 - oxa-thiolane. Suitable catalysts and chain terminators are listed. The Examples describe the polymerization of 1 : 3-oxathiolane, (1), (2) alone, and with (3) mercaptoethanol, (4) methylal, (6) 1 : 3-dioxolane, and (7) dioxolane and glycerol, and of (7) 1 : 3-dioxolane and propylene sulphide.
