Abstract
A rapid, batch Koch carbonylation/functionalization reaction of at least one polymer olefin, carbon monoxide, and an aliphatic or aryl alcohol in the presence of an acid catalyst with either an alcohol:polymer olefin mole ratio .gtoreq.1:1, or an acid catalyst:polymer olefin mole ratio .gtoreq.0.9:1, or both, and recovering at least 80% functionalized polymer which is predominantly ester.
