聚(苯乙烯-乙烯-丁二烯-苯乙烯)三嵌段共聚物(SEBS)接枝马来酸酐,采用的制备方法是溶液法,并考察了反应条件对接枝率的影响。FTIR分析表明马来酸酐基团接到SEBS分子链上,用酸碱滴定法测定了SEBS-g-MAH产物的接枝率,并实验验证了接枝的最佳条件。
Maleic anhydride was grafted by poly (styrene-ethylene-butadiene-styrene) triblock copolymer (SEBS). The preparation method was solution method, and the influence of reaction conditions on grafting rate was investigated. FTIR analysis showed that the maleic anhydride group was attached to the SEBS molecular chain. The grafting rate of SEBS-g-MAH was determined by acid-base titration. The optimum conditions of grafting were also verified by experiments.
