  通过在分子水平上设计水性高分子材料,实现其结构与性能的优化调控是获得有机涂层“耐介质腐蚀等保护性功能”和“耐磨损耐候性等表面性能”一体化要求的有效途径。本文以异佛尔酮二异氰酸酯(IPDI)、二羟甲基丙酸(DMPA)等为主要原料,制得以环氧树脂扩链,丙烯酸羟乙酯(HEA)封端的环氧改性水性聚氨酯(EPU)预聚体,再加入丙烯酸酯单体进行乳液共聚,制备出环氧树脂丙烯酸酯复合改性水性聚氨酯。

环状高分子及含环高分子的几何尺度是表征其结构的重要特征之一,在高分子科学、生物物理学等领域中起着非常重要的作用。本文基于单环的几何结构,构建了环结构在高分子均方回转半径中的统计权重,提出了含环结构高分子均方回转半径的计算方案。
