Abstract

1,134,235. Copolymers of unsaturated esters of galactose. MILK MARKETING BOARD. 10 May, 1967 [18 May, 1966], No. 22069/66. Heading C3P. A copolymer is derived from a vinylidene or vinyl monomer and an ester formed by reaction of an alpha, beta-olefinically unsaturated mono- or di-carboxylic acid with the hydroxy group in the 6-position of galactose. The galactose ester is formed by reacting a 1,2,3,4-diketal of galactose with the unsaturated acid and the diketal residues may be removed from the copolymer by hydrolysis. Specified vinyl and vinylidene monomers are styrene, acrylonitrile, alkyl acrylates and methacrylates, vinyl acetate and vinyl chloride. In Examples 1 to 4, methyl methacrylate is copolymerized with diisopropylidene galactose methacrylate in bulk using azodiisobutyronitrile as catalyst. A similar method is used in Example 7 for the copolymerization of acrylonitrile with diisopropylidenegalactose acrylate and in Examples 9 to 11 for the copolymerization of styrene with diisopropylidenegalactose methacrylate. In Examples 5 and 6, methyl acrylate is copolymerized with diisopropylidenegalactose acrylate in an aqueous emulsion containing sodium lauryl sulphate and ammonium persulphate. Vinyl acetate is copolymerized in Example 8 with diisopropylidenegalactose methacrylate in solution in benzene with azodiisobutyronitrile as catalyst. The copolymers are hydrolysed with formic acid and water and, in some cases, the phenylhydrazone derivatives are then formed.
