Acid-functional polymers derived from anhydride-functional polymers comprising ene reaction products of unsaturated anhydrides and polyolefins and curable compositions prepared from same |
摘要 |
An acid-functional polymer is obtained by the hydrolysis or half-ester ring opening reaction of an anhydride-functional polymer obtained by reacting under ene reaction conditions: (i) an unsaturated anhydride having the structure: <IMAGE> wherein R1 and R2 are each independently hydrogen, alkyl of 1 to about 6 carbons, or alkoxy of 1 to about 6 carbons, or a halogen; and (ii) at least one polyolefin having at least two carbon-carbon double bonds in the polyolefin backbone and having an average of at least three carbon atoms in the polyolefin backbone between the carbon-carbon double bonds. |
