Abstract
A process for preparing a foamed and crosslinked polyethylene resin shaped article having improved heat-sealability, which comprises melt-kneading (a) a silane-modified polyethylene resin, (b) a heat-decomposable blowing agent, (c) a silanol condensation catalyst, and (d) an organic peroxide at a temperature lower than the decomposition temperature of the heat-decomposable blowing agent (b), shaping the mixture, and heating the resulting foamable and crosslinkable shaped articles to the decomposition temperature of the heat-decomposable blowing agent or to a higher temperature thereby to foam and crosslink it; and a foamable and crosslinkable polyethylene resin composition used therefor.
