NAOGOT TVAERBUNDNA SKUMBLANDNINGAR BESTAOENDE AV LINEAERA OLEFINISKA POLYMERER OCH ETT FOERFARANDE FOER FRAMSTAELLNING AV SKUMMEN.

摘要

An expandable blend of a linear olefinic polymer and a crosslinkable polymer for production of lightly crosslinked foamed polymers and a process for the preparation thereof is provided. The presence of a crosslinkable polymer component in the blend increases the melt strength of the linear olefinic component so that conventional melt processing techniques may be utilized to produce foamed polymers. Both open and closed cell foams may be produced.
