摘要：
A styrenic polymer foam contains a polymer composition in the form of a continuous matrix defining multiple cells therein, the polymer composition contains a first polymer and second polymer, the first polymer being a maleic anhydride-grafted high density polyethylene and the second polymer being a styrenic polymer resin that is free of grafted maleic anhydride. The first polymer contains on average 0.05 or more weight-parts of grafted maleic anhydride based on total weight of the first polymer and the concentration of first polymer in the polymer composition is sufficient to provide at least six weight-parts of grafted maleic anhydride per million weight parts of the polymer composition.
