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 1:1, or an acid catalyst:polymer olefin mole ratio 0.9:1, or both, and recovering at least 80 % functionalized polymer which is predominantly ester.

Procédé de carbonylation/fonctionnalisation par réaction rapide et discontinue de Koch d'au moins une oléfine polymère, d'oxyde de carbone et d'un alcool aliphatique ou d'un alcool d'aryle en présence d'un catalyseur acide selon un rapport molaire oléfine polymère:alcool >= 1:1 ou un rapport molaire oléfine polymère:catalyseur acide >= 0,9:1, ou les deux, et récupération d'au moins 80 % du polymère fonctionnalisé présentant une prédominance ester.
