Title:
POLYAMIDE-CELLULOSE RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2021/080010
Kind Code:
A1
Abstract:
Provided are a resin composition in which there is a particularly good achievement of low specific gravity, high rigidity, and a low coefficient of linear expansion, a resin composition in which low specific gravity, high rigidity, a low coefficient of thermal expansion, and low water absorbency are all achieved, are a resin composition which has low specific gravity and in which there is a good achievement of the contradictory properties of high toughness and low thermal expansion. Provided in an embodiment is a resin composition containing a first polymer forming a continuous phase, a second polymer forming a dispersed phase, and cellulose, wherein the first polymer is a polyamide and the second polymer is at least one polymer selected from the group consisting of crystalline resins having a melting point of at least 60 °C and non-crystalline resins having a glass transition temperature of at least 60 °C.
