摘　　要：概述了聚氨酯(PU)结晶性的研究方法,讨论了软硬段种类和结构、硬段含量、软段相对分子质量、带电离子及其它基团和热处理等对PU结晶性的影响,并介绍了结晶性PU在形体记忆材料中的应用状况。The study methods of crystallization in polyurethane （PU） were summarized. The influences of some factors （including type and structure of soft chain segment or hard chain segment, content of hard chain segment, molecular weight of soft chain segment,electriferous ionic and other groups,thermal process and other factors） were discussed on crystallization of PU. The applications of crystal PU were introduced in shape memory material.
