Weather resistant impact modifiers for thermoplastic resins and blends containing the same. |
摘要 |
<p>A weather resistant impact modifier for thermoplastic resins and a blend with the thermoplastic resin are disclosed. The modifier comprises a graft copolymer having a multi-layered structure which is obtained by graft polymerization of (c) 10 - 100 parts by weight of an aromatic vinyl compound or a monomer mixture mainly composed of an aromatic vinyl compound in a first stage and 10 - 100 parts by weight of a methacrylic ester or a monomer mixture mainly composed of a methacrylic ester in a second, stage, (b) to 100 parts by weight of an elastomer obtained by polymerizing 98 - 60 parts by weight of a monomer mixture composed of 50 - 99.95 % by weight of an acrylic ester, 0 - 50 wt% of a copolymerizable monomer and 0.05 - 5 % by weight of a polyfunctional monomer, (a) in the presence of 2 - 40 parts by weight of a butadiene elastomer having a degree of swelling of 5 - 40 and an average particle size of not smaller than 0.15 mu m (wherein the total of (a) and (b) is 100 parts by weight). o</p> |
