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 one 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.
