    摘要: A substantially closed-celled linear polyolefin foam is made by melt processing under pressure a linear polyolefin together with a volatile blowing agent and a cross-linking agent and then expanding the polymer. Suitable cross- linking agents, including azido and vinyl functional silanes, organic peroxides, multifunctional vinyl monomers, and oxygen, increase the melt tension and melt viscosity of the polymer by lightly cross-linking the polymer with itself to enable the production of foams having improved properties in comparison with branched polyolefin foams.
