聚合物及其制造方法、成形材料和成形体
Abstract:
通过使用将包含以下(a)～(c)的单体混合物(α)悬浮聚合得到的聚合物(D)，能够得到透明性优异的成形体。(a)特定的大分子单体5～60质量％；(B)具有与大分子单体(a)的溶解度参数之差为0.25以上的溶解度参数的均聚物(B)的原料单体5～60质量％；(c)具有与大分子单体(a)的溶解度参数之差不足0.25的溶解度参数的均聚物(C)的原料单体10～80质量％。
Abstract(English):

A molded product with excellent transparency can be obtained by using a polymer (D) obtained by suspension polymerization of a monomer mixture (1) containing (a) to (c) below: (a) 5-60 mass% of a specific macromonomer; (b) 5-60 mass% of the raw material monomer of a homopolymer (B) that has a solubility parameter that is different by 0.25 or more from the solubility parameter of the macromonomer (a); and (c) 10-80 mass% of the raw material monomer of a homopolymer (C) that has a solubility parameter that is different by less than 0.25 from the solubility parameter of macromonomer (a).
