水化纤维素膜化学方法接枝共聚研究

首先对水化纤维素膜接枝共聚原理进行了分析,并在此基础上对水化纤维素膜采用化学方法与多种类型单体进行接枝共聚进行了实验,以期进一步提高共聚物材料的亲水性和耐碱能力。经过理论分析和初步筛选后,发现2-丙烯酰胺-2-甲基丙磺酸(AMPS)单体与水化纤维素膜接枝共聚后,可以达到改善共聚物材料的亲水性和耐碱能力的目的。同时也以AMPS单体为切入点,对影响水化纤维素膜接枝的各种外部因素进行了探讨,为进一步研究水化纤维素膜通过化学方法接枝共聚提高性能奠定了基础。

Research on copolymerization with chemical method of engrafting to cellulose hydrates membrane

The principle of copolymerization with method of engrafting to cellulose hydrates membrane was analyzed.And according to the analysis,the chemical experiments to promote copolymers’hydrophilicity and resistance to alkali were carried out through the way of copolymerization between cellulose hydrates membrane(CHM) and several types of monomers separately.After analyzing and selecting the data theoretically,it is found that the graft copolymerization between 2-acrylamide-2-methylpropane-sulfonic acid(AMPS) and CHM can realize the expectation of promoting copolymers’ ability of hydrophilicity and resistance to alkali.In addition,the external factors which influenced CHM’s graft were discussed based on AMPS.Some experiences and data for further study of promoting the ability of copolymers of chemically engrafted CHM were offered.
