摘要： A foamed, non-crosslinked resin particle having a bulk density of not greater than 0.045 g/cm 3 and an average cell diameter of at least 200 pm. The non-crosslinked resin includes a polypropylene resin to which a vinyl comonomer is graft-polymerized in such an amount that the weight ratio of the polypropylene resin to the grafted polymer of the vinyl comonomer is in the range of 97:3 to 65:35. The foamed resin particles are produced by grafting a vinyl comonomer to polypropylene resin particles at a temperature of less than 90°C in the presence of a specific radical polymerization initiator to obtain modified polypropylene resin particles and, then, expanding the modified polypropylene resin particles. The initiator used requires a temperature of not higher than 70°C for obtaining a half life of 10 hours.

Further, the present uncrosslinked polyethylene expanded particles are obtained by impregnating the above resin particles with an expanding agent, dispersing the resin particles in a dispersing agent in a closed vessel, and discharging the resin particles and the dispersing medium from the vessel at a temperature equal to or over the softening temperature of the resin particles into a low-pressure region.

摘要： A process for the production of expanded beads, including kneading a base resin containing a polypropylene resin and having a tensile modulus of at least 1,200 MPa together with a mixture of a coloring agent and a thermoplastic polymer having a tensile modulus lower than that of the base resin to form a kneaded mixture including a matrix of the base resin and a multiplicity of domains dispersed in the matrix and each containing the thermoplastic polymer and the coloring agent. The kneaded mixture is formed into resin particles, then treated with an organic peroxide to modify surfaces of the resin particles therewith. Foaming and expanding of the surface-modified resin particles gives expanded beads having an inside region surrounded by a surface region. The heat of fusion of a high temperature peak of the surface region is lower than that of the inside region.
