Abstract
An amine functional copolymer of vinyl alcohol is provided by copolymerizing a vinylester with a morpholinoalkylvinylether or a morpholinoalkylallylether and then hydrolyzing the ester groups in the copolymer to hydroxy groups. The preferred copolymer is formed from vinyl acetate and morpholinoethylvinylether and 1 to 30 mol percent of the polymerized ethylene linkages in the polymer backbone contain pendant morpholinoethylether groups.
