摘要：
Terpolymers of a lower olefin, a vinyl ester and a 2-ene-carboxylic acid are reacted with water at elevated temperatures to produce a polyolefin containing multiple olefinic unsaturation and carboxylic acid groups. Ester groups are converted to olefinic unsaturations by elimination of acid such as acetic acid.The carboxylic acid groups give the product polymer emulsifiability in water, while the double bonds cause the polymer to be sensitive to ultraviolet light and suitable as chemical intermediates for further reaction at the sites of the double bond.
