摘要

本文采用在聚氨酯中引入丁基二乙醇胺

形成带有叔氮原子的聚氨酯(NPU)和聚甲基丙烯酸甲酯中引入甲基丙烯酸的方法

合成了带有离子键的离子聚合体型互穿聚合物网络(IPN)

动力学研究表明

离子聚合体型IPN形成速率明显低于非离子聚合体型IPN

两网络的聚合速率相互抑制

并随离子键浓度增加而显著

两网络的聚合机理互不干扰。

Abstract

Polyurethane/methyl methacrylate copolymer interpenetrating polymer networks with opposite charge groups (ionomer IPNs) were synthesized from NPU and PMMA-MAA

NPU was prepared from poly(oxyethylene) glycol

4-tolylene diisocyanate and bis (2-hydroxy ethylene) butylamine

PMMA-MAA was prepared by copolymerization of methyl methacrylate and methacrylic acid. The results of kinetics study showed that the formation rate of ionomer IPNs was slower than that of usual IPNs

the polymerization rate of two networks restrained one another

and increased with concentration of ionic bond. However

the poly-merization mechanisms of two networks were not affected.
