Abstract
1,174,097. Modified polyvinyl alcohols. DUNLOP CO. Ltd. 31 Aug., 1967 [3 Sept., 1966], No. 39469/66. Heading C3P. A modified polyvinyl alcohol is prepared by subjecting to acid hydrolysis an aqueous emulsion of a copolymer obtained by copolymerization of at least one readily-hydrolysable vinyl ester monomer and a vinyl ester monomer in which the carbon atom attached to the carbonyl group is quaternary, this second vinyl ester being difficultly-hydrolysable and being present in an amount of 0À1 to 40% by weight based on the total weight of the monomers, to obtain an aqueous solution of a modified polyvinyl alcohol product in which the second vinyl ester units and some of the ester linkages of the readily-hydrolysable monomer are not hydrolysed. The " readily-hydrolysable " monomers are capable of being 97% hydrolysed within 1 hour by refluxing with N 12 alcoholic potash. The hydrolysis may be aided by adding an alcohol which reacts with the carboxylic acid produced and removing the ester so formed. Suitable acid catalysts are alkyl benzene sulph. onic acids having an alkyl group of 10 to 14 carbon atoms, phosphonic acids, organic acid phosphates having an alkyl chain of 10 or more carbon atoms, sulphuric acid or para-toluene sulphuric acid. The modified polyvinyl alcohol solution may be spray dried or further treated to produce a solid product. The solid product or the solution may be treated with an aldehyde containing at least two carbon atoms, e.g. butyraldehyde to produce a polyvinyl acetal. In the examples a copolymer produced by polymerization of viny acetate and a vinyl ester of branched chain C 9-11 fatty acid using polyvinyl alcohol as emulsifier and hydrogen peroxide with or without fibrous ion as initiator is hydrolysed using dodecyl benzene sulphonic acid, sulphuric acid, water and methanol.
