摘要
指出影响ＰＵ弹性体耐水性能的主要因素是软段（聚酯、聚谜）和分子量，硬段（二异氰酸酯、扩链剂）和浓度、聚酯的碳链长度和酸值以及浸水温度和湿气温度等。讨论这些因素对ＰＵ浸水、湿气老化后的某些力学位能的影响。
A review is cited with 12 references.Effects of soft segments and molecular weight,hard segments and concentration,polyester acid numbers,and environmert on some mechanical properties of PU elastomer of immersion aging and humidity aging were discussed.
