CA 2222333
Concentrates produced by melt processing a branching agent and a polyester carrier are disclosed. The concentrates are useful in melt processing polyesters. The concentrates contain sufficiently high concentrations of a branching agent to minimize the formation of crosslinked compounds in the concentrates. Process for using the concentrate also is disclosed.
