Synthesis of multi-functional hyperbranched polymers by polymerization of di-or tri-vinyl monomers in the presence of a chain transfer catalyst

摘要

This invention concerns the synthesis of multi-functional hyperbranched polymers by free radical polymerization of di- or tri- vinyl monomers in the presence of a chain transfer catalyst and a non- peroxide free radical initiator. The low viscosity and high functionality of these polymers make them useful for automotive coatings and for photopolymerization applications.
