Abstract
A Koch functionalized product which is the reaction product of at least one polymer having a number average molecular weight of at least 500 and at least ethylenic double bond per polymer chain, with carbon monoxide and a nucleophilic trapping agent. The invention includes functionalized polymer, derivatives thereof and methods of making the same.
Claims25
A process for preparing a functionalized polymer containing acyl functional groups selected from carboxylic acids, carboxylic esters and thioesters, comprising the step of reacting in admixture:
- (a) at least one polymer having a number average molecular weight of at least about 500, and at least one ethylenic double bond per polymer chain,
- (b) carbon monoxide,
- (c) and a nucleophilic trapping agent selected from the group consisting of water, hydroxy containing compounds and thiol containing compounds, the reaction being conducted in the presence of an acid catalyst having a Hammett acidity of less than about -7.
