Graft copolymers of lactone polyesters

摘要

Various ethylenically unsaturated monomers can be graft copolymerized onto lactone polyesters, such as, homopolymers of epsilon -caprolactone or copolymers of epsilon -caprolactone and epsilon -alkyl- epsilon -caprolactones at temperatures between 90 DEG and 150 DEG C. The resultant graft copolymers can be used as plasticizers for polyvinyl chloride resins.
