摘要/Abstract

摘要：

以三羟甲基丙烷(TMP)为内核, 二羟甲基丙酸(DMP)为支化单元用准一步法合成了重均分子量为12100的第四代端羟基脂肪族超支化聚酯G4, 并与聚甲基三乙氧基硅烷(PMSQ)共混制备出一系列不同质量分数的复合物. 利用固体核磁共振(NMR)等方法表征了各个样品的结构和反应程度, 并通过测量¹H T_1ρ值发现超支化聚酯与聚倍半硅氧烷之间具有较好的相容性, 相容尺寸为3~5 nm.

Abstract:

A hydroxyl group ended hyperbranched polyester generation 4(G4) with trimethylolpropane(TMP) as a core and 2,2-dimethylol propionic acid(DMP) as a branched monomer weighted about 12100 was synthesized by a semi-one pot method. G4 was introduced into polymethyl silsesquioxane(PMSQ) system, and a series of G4/PMSQ composite membranes were prepared. Solid state NMR was used to characterize the structures of the composites. By measuring the ¹H T_1ρ, the miscibility of the two components of the composite was also studied.

Key words: Hyperbranched polyester; Polysilsesquioxane; Solid state NMR; Miscibility
