摘要

通过“逐步偶联聚合方法”设计合成了一种含有反应性侧基的梯形聚有机硅氧烷。此合成方 法采用N,N′二(1,1-二甲基-2-羟乙基)对苯二甲酰胺(M)为模板,将具有三官能团 的有机硅单体联结成梯形模板单元,然后在N—H…O〖FY=,1〗C型氢键作用下水解缩合,得 到一种具有高规整性的梯形聚硅氧烷。通过XRD和29Si-NMR,对该化合物的组成和结 构进行了表征。结果表明,该化合物具有规整的梯形结构。上述含有反应性侧基的梯形聚有 机硅氧烷可以作为潜体进一步制备其它功能性高分子。

Abstract

A novel ladderlike polysiloxane with a reactive side group was synthesized via s tepwise coupling polymerization. During the reaction, the coupling agent N,N′-di (1,1-dimethylethanol)terephthaloyl amide (abbreviated as M) is believed to act as a template which enables silane molecules to form a ladderlike supramole cular intermediate through amido Hbonding interactions, followed by further co ndensation to form amidebridged ladderlike polysiloxanes. The structure of the polymer was characterized by X-ray diffraction and 29Si-NMR. The da ta show that the polymer has an ordered ladderlike molecular structure. The titl e polymer, ladderlike polysiloxane with grafted reactive groups is a very promis ing and potential precursor for the preparation of new functional polymers.
