摘要： A substantially water-impermeable polyolefin foam made of expandable polyolefin beads. The polyolefin foam is prepared by a particular process in which after heating expandable polyolefin beads and before cooling the heated beads in a mold, the heated beads were allowed to stand in the state that the polyolefin resin maintains the flowability.
