EXPANDED POLYPROPYLENE RESIN BEAD AND PROCESS OF PRODUCING SAME |
摘要 |
Expanded, substantially non-crosslinked polypropylene resin beads capable of producing a high rididity foamed molding at a relatively low temperature. The beads are produced by a process including a step of dispersing substantially non-crosslinked polypropylene resin particles in a dispersing medium containing an organic peroxide to obtain a dispersion, a step of heating the dispersion to decompose the organic peroxide and to modify the surface of the surface-modified polypropylene resin particles, and a step of expanding the non-crosslinked, surface-modified polypropylene resin particles using a blowing agent.
