摘　　要：随着科学技术的进步,材料科学有了很大的发展,其中高分子材料的发展应用尤为迅速。许多高分子材料在新的环境下结构与性能之间的关系都有待于研究。因此,了解它们在一些极端条件下(如高温高压、低温低压等),结构与性能之间的变化规律是十分必要的。高压对聚合物材料的结构与性能有较大的影响。国内外学者主要对聚烯烃、聚酯、聚酰胺等聚合物及其复合体系的高压结晶和高压退火行为进行了一系列研究工作。本文介绍了这一领域的研究概况和最新进展。With the advancement of science and technology, materials science has greatly developed. Especially,the development and application of polymer materials are considerably fast. The relationship between structure and properties in the new application environment has to be studied for many polymer materials. Therefore, it is very necessary to understand the variation of structure and properties of these polymer materials under some extreme conditions （high temperature and pressure, low temperature and pressure et al. ）. The structure and property of polymer materials are significantly affected by high pressure. A series of studies have been made on the crystallization and annealing of polyolefin,polyester, polyamide and so on under high pressure by scholars from home and abroad. A review of researc＇h progress in this filed is introduced in this paper.
