FOAMABLE OLEFIN POLYMER COMPOSITIONS STABILIZED WITH CERTAIN HIGHER ETHERS, ESTERS OR ANHYDRIDES, FOAMING PROCESS USING THEM AND FOAM ARTICLE PRODUCED

摘要

Substantially closed-cell aliphatic olefin polymer foams having improved dimensional stability are provided by the inclusion therein of from 0.1 to 10 weight percent, based upon the olefin polymer, of certain higher aliphatic hydrocarbyl ether, ester or anhydride compounds.
