摘要: Polypropylene-based resin extruded expanded particles have a low open cell ratio and are inexpensively obtainable. The polypropylene-based resin extruded expanded particles are obtained by extrusion expansion of a resin composition that contains a polypropylene-based resin (A) which has a branched structure and a polypropylene-based resin (B) in which a branched structure is not introduced. Furthermore, the polypropylene-based resin (B) has a weight average molecular weight of not less than 500,000 and a flexural modulus of not less than 950 MPa.

摘要: A method for producing modified polystyrene-based resin particles from which a foamed molded product having little variation in crack resistance can be obtained is provided. The method for producing modified polystyrene-based resin particles includes a polymerization step of obtaining modified polystyrene-based resin particles by copolymerizing a styrene-based monomer and a conjugated diene-based monomer which are impregnated into polystyrene-based resin particles. The polymerization step includes adding a polymerization initiator dissolved in a solvent having an SP value in a specific range and 8 or less carbon atoms.
