摘　　要：以甲苯为溶剂、偶氮二异丁腈为引发剂,通过沉淀聚合法制备了苯乙烯-马来酸酐共聚物,并测定共聚物中酸酐的含量。以丙酮为溶剂,对甲苯磺酸为催化剂,在苯乙烯-马来酸酐共聚物中加入聚氧乙烯醚改性剂,回流条件下合成了以苯乙烯-马来酸酐为主链,聚氧乙烯醚链为侧链的改性聚合物,使用傅立叶红外光谱对其结构进行表征。The copolymer of styrene （St） and maleic anhyd with azobisisobutyronitrile as the initiator and toluene as the copolymer was measured by titration. The modified polymer with ride （MAH） were prepared by precipitati solvent. Furthermore, the content of poly（styrene-maleic anhydride） as the b on polymerization anhydride in the ackbone chain and polyoxyethylene ethers as the side chain was formed by adding polyoxyethylene ether modifier into the St-co-MAH copolymer under reflux in acetone using p-toluenesulfonic acid as the catalyst. Its structure was characterized by Fourier transform infrared spectroscopy
