ABSTRACT:
A Koch functionalized product, which is the reaction product of at least one hydrocarbon with carbon monoxide and a nucleophilic trapping agent, is derivatized with a heavy polyamine and a second amine. The hydrocarbon is a hydrocarbon compound or a hydrocarbon polymer. A heavy polyamine is a mixture of polyamines containing small amounts of lower polyamine oligomers such as tetraethylene pentamine and pentaethylenehexamine and containing primarily oligomers with more than 6 nitrogens and more extensive branching. Rubber seals embrittlement is reduced or minimized.
