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.
