High Impact Polymers and Methods of Making and Using Same

摘要

A method comprising contacting a grafting polymerization initiator with a composition comprising a vinylaromatic monomer and an elastomer under conditions suitable for the formation of a polymeric composition and forming the polymeric composition into an article wherein the article has an Izod impact strength of greater than 2.0 ft. lb./in. A method comprising contacting a grafting polymerization initiator with a vinylaromatic monomer and an elastomer under conditions suitable for the formation of a polymeric composition, wherein the grafting polymerization initiator comprises a peroxyketal.
