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