Abstract

An improved method of free radical polymerization conducted in the presence of a relatively low molecular weight macromonomer such as can be made with a metal chelate chain transfer catalyst. This method has various uses, including reducing the molecular weight of a variety of crosslinkable polymers and copolymers.
