摘要： A modified polymer rubber is obtained by
(1) graft-polymerizing at least one grafting monomer to a shredded rubbery polymer (A) in an aqueous suspension at a temperature of 30° - 130°C to obtain a graft polymer, and
(2) kneading the graft polymer with at least one polymerizable monomer in the presence of a free radical initiator at a temperature of 180°-280°C. This process does not cause gel formation and is advantageous in manufacturing cost.
The modified polymer rubber thus obtained is excellent in processability and storage stability, and highly useful as a compatibilizer for various resins.摘要翻译： 通过（1）在30〜130℃的温度下在水性悬浮液中将至少一种接枝单体接枝聚合到切碎的橡胶状聚合物（A）上得到改性聚合物橡胶，得到接枝聚合物，（2） 在180℃-280℃的温度下，在自由基引发剂的存在下，将接枝聚合物与至少一种可聚合单体捏合。该方法不会导致凝胶形成，并且制造成本有利。 由此得到的改性聚合物橡胶的加工性和保存稳定性优异，作为各种树脂的增容剂是非常有用的。
