複合樹脂粒子
Document Type and Number:
Japanese Patent JP6964962
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide composite resin particles which can obtain a foam resin molded body that has good internal fusion, is hardly fatigued, is excellent in deflection resistance, and can prevent breaking caused by deformation, have a less residual styrenic monomer, and are excellent in foaming properties at the time of foaming and in forming properties at the time of forming.SOLUTION: Composite resin particles 1 contain a composite resin, in which an ethylenic resin is impregnated and polymerized with a styrenic monomer, as a base material resin. The composite resin contains more than 400 pts.mass and 1,900 pts.mass or less of a structural unit derived from a styrenic monomer with respect to 100 pts.mass of the ethylenic resin. A content of the styrenic monomer existing in the composite resin particles as a monomer is 0-500 mass ppm. A content ratio Wof a xylene insoluble matter in the composite resin particles 1 is 0-40 mass%.SELECTED DRAWING: Figure 2
