摘要： A novel acrylic thermoplastic resin composition, transparent and excellent in flexibility, consisting of at least two different multi-layer structure polymers. Polymer [I] contains an inner layer of crosslinked acrylic elastomer and an outer layer of acrylic resin, wherein the amount of elastomeric inner layer is minor in comparison with the amount of the resin outer layer; polymer [II] has the same fundamental polymer structure as multi-layer structure polymer [I] except that the amount of crosslinked elastomer inner layer is a major amount as compared to the amount of resin outer layer. It is preferred that an intermediate layer having an intermediate property exist between the inner and outer layers of the multi-layer structure polymers.
摘要翻译：一种由至少两种不同的多层结构聚合物组成的透明且柔软性优异的丙烯酸类热塑性树脂组合物。聚合物[I]含有交联的丙烯酸弹性体的内层和丙烯酸树脂的外层，其中弹性体内层的量与树脂外层的量相比较小; 聚合物[II]与多层结构聚合物[I]具有相同的基本聚合物结构，除了与树脂外层的量相比，交联的弹性体内层的量是主要量。优选在多层结构聚合物的内层和外层之间存在具有中等特性的中间层。
