RUBBER-REINFORCED VINYL RESIN, PROCESS FOR PRODUCING RUBBER-REINFORCED VINYL RESIN, AND RUBBER-REINFORCED VINYL RESIN COMPOSITION

摘要

A rubber-reinforced vinyl resin which is obtained by polymerizing a vinyl monomer in the presence of a rubber-like copolymer comprising at least two members selected from (I) an ethylene- alpha -olefin based rubber having a Mooney viscosity of 15 or higher, (II) an ethylene-octene based rubber having a Mooney viscosity less than 15, and (III) an ethylene-octene based rubber having a Mooney viscosity of 15 or higher; a process for producing the resin; and a composition containing the rubber-reinforced vinyl resin. They are excellent in moldability and gives a molded articles which are excellent in appearance in terms of gloss, flow marks, weld appearance, color unevenness at welded portions, colorability and the like, and excellent in impact resistance, for example, impact resistance at low temperatures as well as in weatherability.
