Plasticization of polymers by supercritical CO_2 and its application

Xia Yuan-jing

Abstract

The characteristics of supercritical CO_2 and its interaction with polymer are introduced. The applications of the plasticication of polymer by supercritical CO_2 are discussed, it includes: penetration of small molecule, swollen polymerization, extraction fractionation of polymers, supercritical fluid devolatilization and the preparation of micro-cellular polymers etc.
