摘要： Production of flexible expanded moldings from olefin polymers by heating a mixture comprising an olefin polymer, a peroxide and a solid expanding agent in a mold, which is gastight when closed and is filled with a volume of said mixture equal to from 95% to 100% of its capacity, to a temperature above the softening point of the olefin polymer and above the decomposition temperature of the peroxide and of the expanding agent, starting to release the pressure in the mold to atmospheric pressure, immediately increasing the volume of the mold to from 3 to 35 times the volume of the expansible melt within from 0.1 to 20 seconds and then cooling the expanded molding. The moldings are used as thermal and sound insulating materials and as upholstery padding.
