摘要：
A process for producing a crosslinked foam having uniform, fine, open cells, which comprises foaming an expandable composition comprising a crosslinkable polyolefin resin, 20 to 60 % by weight of an amorphous propylene polymer, a foaming agent and a crosslinking agent, by a one-step heat-press method. According to said process, a crosslinked foam having an open cell percentage of 40% or more can be obtained by a one-step treatment.
