摘要

微孔聚合物是80年代初发明的一种新型材料，在90年代由于超临界CO

的使用而得到了很大发展，并被誉为“二十一世纪的新型材料”。本文介绍了微孔聚合物的基本制备方法、结构特点和性能，以及研究现状。特别介绍了在微孔聚合物制备中应用超临界CO

的优点，详细介绍分步快速升温法、快速降压法和连续法的基本过程和研究成果，并对微孔聚合物的进一步发展进行了展望。

Abstract

Microcellular polymers

as a group of foamed materials invented in 1980s have got a great development in 1990s due to the application of supercritical CO

in their processing.They are usually called as "novel materials for 21 Century" .In this review

the preparation

structure and properties of microcellular polymers

theoretical progress are summarized.The advantages of using supercritical CO

in making microcellular polymers are emphasized.A detail description of basic methods

such as batch method

pressure quenching method and continuous method

is presented together with the progress in the research of these methods. Finally

the futrue of microcellular polymers is also predicted.
