Abstract

Compositions are disclosed that are the urea derivatives of succinylated polyolefins (maleated polyolefins). The urea derivatives of succinylated polyolefins are of the formula; ##STR1## wherein R is a polyolefin attached at any point along the hydrocarbon chain. The urea derivative of succinylated polyolefins is useful as a coupling agent to couple polyolefins with dissimilar polymers having an excess of unreacted acid groups such as polyesters.
