Abstract

Polymers of improved colour are made by the polymerization or co-polymerization of a C1- 5 alkylvinyl pyridine which is stabilized by the addition thereto of a mixture of (A) 1,2-dihydroxy-4-t-butyl benzene and (B) one or more of acrylonitrile or an alkyl acrylate of the formula <FORM:1085920/C3/1> where R is hydrogen or a methyl group and R1 is an alkyl group, provided that when R1 represents an alkyl group of 2 or more carbon atoms, the amount of alkyl acrylate is at most 0.5% by wt. based on alkylvinylpyridine. Example 29 describes the preparation of a copolymer of acrylonitrile, methyl acrylate and stabilized 2-methyl-5-vinyl pyridine, using hydrogen peroxide as catalyst and 1-thio-glycerol as an activator.ALSO:C1- 5 monoalkyl vinyl pyridines are stabilized by addition of a mixture comprising (A) 1,2-dihydroxy-4-t.-butyl benzene and (B) one or more of acrylonitrile and alkyl acrylates of the formula <FORM:1085920/C2/1> where R is hydrogen or a methyl group and R1 is an alkyl group, with the proviso that when R1 represents an alkyl group of 2 or more carbon atoms, the amount of alkyl acrylate in the composition is at most 0.5% by weight based on alkyl vinyl pyridine. When component (B) is acrylonitrile the mixture may also contain vinyl acetate. Examples relate to the stabilization of 2-methyl-5-vinyl pyridine.
