摘　　要：通过同步法制备了一系列聚氨酯／乙烯基酯树脂互穿聚合物（ＰＵ／ＶＥＲ－ＩＰＮ），研究了ＰＵ／ＶＥＲＩＰＮ性能的影响因素。结果表明：随着ＰＵ含量的增加，ＩＰＮ的热稳定性能有一定程度的提高；而ＶＥＲ的含量增加，ＰＵ／ＶＥＲ－ＩＰＮ的剪切强度提高。实验还发现：当ＰＵ／ＶＥＲ－ＩＰＮ为部分相容的多相微区结构时。A series of PU/VER INPs was prepared by means of simultanuous polymerization,and the structure and property of the PU/VER INPs were studied by means of TG,DMTA and TEM.The results showed the thermostability of the IPNs was improved with the increase of PU content in the IPNs,and the shearing strength increased with the increase of VER content.It was also found semicompatible IPN showed better damping propery.
