NON-LINEAR STYRENIC POLYMER-BASED FOAM

摘要

PROBLEM TO BE SOLVED: To provide a process for preparing a low density aromatic polymer foam from a non-linear monovinyl aromatic polymer using an environmentally more acceptable blowing agent. SOLUTION: A process for preparing a low density closed-cell polymer foam comprising a plurality of closed cells having an average cell size of at least about 0.08 millimeter (mm) is provided.
