ABSTRACT:
A polyolefinic resin is combined with a (meth)acrylic polyfunctional monomer compound having an aromatic ring, an alicyclic ring or a heterocyclic ring nearly in the center of its chemical formula, and a pyrolyzable chemical foaming agent to give a curable and foamable polyolefinic resin composition. The composition is shaped into a sheet, then cured and foamed into a sheet foam. The cured foam of polyolefinic resin has a curing degree of from 10 to 70%, and has the advantages of good heat resistance, good workability and shapability, and good pressure resistance.
