摘要

本文研究了聚苯乙烯-丁二烯-4-乙烯基吡啶嵌段共聚物经,60,Coγ辐照后的性能，实验表明当辐照剂量为10,5,Gy时，嵌段共聚物的凝胶含量达98%。此时共聚物有优良的耐酸、硷、有机试剂性能。FTIR红外光谱证实辐照（剂量10,5,Gy）后共聚物中双键峰基本消失。TEM照片表明辐照不改变嵌段共聚物的相分离结构。和未辐照的样品相比，辐照后聚合物的断裂模量提高一倍，断裂形变则下降1/5，并且聚合物的应力松弛也减小。聚合物的扬氏模量在0—60℃范围内保持不变（10,10,dyn•cm,-2,）。上述特点使得辐照后的嵌段聚合物极有利于制成嵌镶离子交换膜。

Abstract

The present study has been carried out with a view to show the properties of poly(styrene-butadiene-4-vinylpyridine) triblcck copolymer irradiated by ,60,Co gamma-ray. The experiments reported here have indicated that the content of gel in polymer is above 90% when irradiation dose is 10,5, Gy.Meanwhile, FTIR spectra of copolymer by irradiated confirm the double bonds in polybutadiene domain are disappeared and TEM spectra of copolymer before and after irradiation reveal the morphology of copolymer dose not effected by irradiation.The research has been done demonstrates the Poly(styrene-butadiene-4-vinylpyridine) triblock copolymer irradiated by gamma-ray have advanced properties to withstand chemical agents, strong acid and alkali. On the other hand, comparing with the unirradiated polymer, the polymor irradiated by gamma-ray exhibits higher stress and lower strain. The elastica modulus of polymer irradiated by gamma-ray keeps unchange from 0 to 60℃. From this experiments one came to realize poly(styrene-butadiene-4-vinylpyridine) triblock copolymer irradiated by gamma-ray are favourble for fabricating charge-mosaic membrane, which could be used in desalination and purification of biochemicals.
