Title: Graft copolymers of methylene lactones and process for emulsionpolymerization of methylene lactones

Abstract: This invention discloses resilient, acrylic graft polymers comprising .alpha.-methylene lact(one)(am) monomers such as .alpha.-methylene-.gamma.-butyrolactone, and blends of such polymers with thermoplastic matrix resins.This invention also discloses hard, non-resilient, acrylic graft polymers comprising .alpha.-methylene lact(one)(am) monomers such as .alpha.-methylene-.gamma.-butyrolactone, and to blends of such polymers with thermoplastic matrix resins.This invention further discloses a general process for emulsion polymerization of .alpha.-methylene lact(one)(am) monomers such as .alpha.-methylene-.gamma.-butyrolactone and its copolymers.
