摘　　要：以偶氮二异丁腈(AIBN)为引发剂,合成了一系列马来酸酐/丙烯酸正丁酯共聚物.分析研究其共聚反应历程,探讨了反应时间、单体配比等因素对聚合反应的影响.进一步对共聚产物进行元素分析,并测定了相应共聚物的玻璃化转变温度.结果表明:该聚合反应主要是交替共聚反应.共聚物中的BuA含量随着BuA单体配比的增加而增加;共聚物的玻璃化转变温度随BuA在共聚物中摩尔分数的增加呈下降趋势.A series of Maleic anhydride-butyl acrylate copolymers were synthesized by using AIBN as initiator. The study emphasized on the process of the copolymerization of different molar ratios. The effect of the reaction lime and mole ratio of monomers on the copolymerization was investigated, The copolymers were analyzed by the elementary instrument, and their glass transition temperatures were detemined. The results show that the copolymerization is mainly an alternating one, With the increase of the mole ratio of butyl acrylate in reactant, the content of butyl acrylate in the resulting copolymers increases, and the glass transition temperature of copolymer decreases as the mole ratio of butyl acrylate in copolymer increases.
