Title:
COMPOSITE PARTICLES AND RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2020/050286
Kind Code:
A1
Abstract:
The purpose of one embodiment of the present disclosure is to provide: composite particles which contain fine cellulose and impart a molded body with physical property stability that is good enough for practical use, while imparting the molded body with sufficient mechanical characteristics; and a resin composition which contains the composite particles. One embodiment of the present disclosure provides composite particles which contain fine cellulose and a thermoplastic resin, and which is configured such that: the ratio of the fine cellulose in the composite particles is from 10% by mass to 95% by mass (inclusive); and a dispersion liquid, which is obtained by dispersing the composite particles into dimethyl sulfoxide so that the fine cellulose concentration in the dispersion liquid is 1% by mass, has a viscosity η10 at a liquid temperature of 25°C at a shear rate of 10 s-1 is 10 mPa·s or more.
