Abstract
1351647 Vinyl pyridine polymer-lactone reaction products DENKI ONKYO CO Ltd 9 July 1971 [9 July 1970] 32404/71 Heading C3P A polymer containing vinyl pyridine or alkyl-substituted vinyl pyridine units is reacted with #-propio-lactone with formation of polyester side chains on at least one pyridine nucleus to give an amphoteric, biionic product. The product may be hydrolysed with strong acids or bases and the product neutralized or rendered acidic or basic with further acids or bases; the product may also be neutralized directly with weak acids and bases. In examples 2-vinyl pyridine, 3-vinyl pyridine, 4- vinyl pyridine, 5-ethyl-2-vinyl pyridine, 2- methyl-4-vinyl pyridine, 2-vinyl pyridine/3- vinyl pyridine, 3-vinyl pyridine/styrene, and 2-vinyl pyridine/acrylonitrile polymers are prepared using benzoyl peroxide or azobis isobutyronitrile in bulk or in aqueous or organic medium. The polymers are reacted with the #-propiolactone under mild heating conditions in solution. The products are then in some cases hydrolysed and/or neutralized and in each form may be used as polymer electrolytes.
