摘要

用紫外光聚合方法制备出一系列端乙烯基聚己二酸乙二醇酯聚氨酯(PEAPU)和甲基丙烯酸甲酯(MMA)AB交联聚合物(ABCP)。用粘弹谱仪、透射电子显微镜(TEM)和平衡溶胀法研究了AB交联聚合物的动态力学性能、玻璃化转变温度、形态和交联密度、观察到相应于聚氨酯和PMMA相两个玻璃化转变温度

TEM照片中的微相分离是更明显的

ABCP中的两个T_g内移表明

两种成分的化学交联增加了相互的可混性、与ABCP具有相同组成的IPN有比ABCP大得多的相区。氢键能够影响ABCP的相容性、形态和动态力学性能。

Abstract

A series of UV-cured AB crosslinked polymers (ABCP) based on vinyl-terminated polyethylene adipate polyurethane and methyl methacrylate were prepared. The dynamic mechanical properties

glass transition

morphology and crosslinking density of the AB crosslinked polymers were studied by using Rheovibron

TEM and equilibrium swelling. Two glass transition temperatures

corresponding to these of polyurethane and PMMA phases were observed and mic-rophase separation was eventually evident with TEM. The two Tgs were shifted inwardly in ABCP indicating that the chemical crosslinking between wo components increased the mutual miscibility. IPN with similar composition to ABCP have much larger phase domains than ABCP. Hydrogen bond influenced greatly the compatibility

morphology and dynamic mechanical pro-perties of ABCP.
