ABSTRACT:
In producing a crosslinked polypropylene foam, 0.5 to 4 parts by weight of a compound selected from triacrylate and trimethacrylate of aliphatic polyhydric alcohol and a blowing agent are mixed with 100 parts by weight of propylene homopolymer or copolymer. Then, the mixture is shaped under heat, followed by irradiation with an ionizing radiation such that the dose of the radiation absorbed by the shaped mass ranges between 0.1 and 10 Mrad. Finally, the irradiated mass is heated for foaming.
