摘要: Foam moldings of olefin polymers are prepared by heating, and pressing together, foamed particles of an olefin polymer, containing crosslinked constituents, in molds, a temperature gradient of from 0.5.degree. to 25.degree. C per cm of loose mass of particles being established in the mold, which has a gas-permeable wall on the lower-temperature side.
