Document Type and Number:
WIPO Patent Application WO/2020/138501
Kind Code:
A1
Abstract:
Provided is a multilayer-structured polymer particle having excellent long-term thermal stability in a matrix resin (base resin), and an excellent dispersibility and impact resistance in order to reduce defects in a molded body including a film. The multilayer-structured polymer particle has: an inner layer containing a cross-linked rubber (I); and an outer layer containing a thermoplastic resin (II) which is grafted with the inner layer, wherein the ratio [V2/V1] of the mass (V2) of the outer layer to the mass (V1) of the inner layer is 0.3-0.8, and the glass transition temperature of the outer layer is 80-120 °C.
