摘　　要：以顺丁烯二酸酐和碳酸铵作为聚合原料,采用双螺杆挤出机作为聚合反应器制备了聚琥珀酰亚胺产品,研究了催化剂、反应温度、物料配比和螺杆转速对反应的影响。用FT-IR对其进行了结构表征,并用极限粘度法测定了聚琥珀酰亚胺的聚合度。结果表明,最佳合成条件为n(顺酐)∶n(碳酸铵)∶n(催化剂)=1∶1.5∶0.07,聚合温度为180、195、210℃,螺杆转速为60 r/min。该条件下的聚琥珀酰亚胺的聚合度可以达到276,单体转化率为91.6%。方法原料易得、操作简单、条件温和、无污染,为聚琥珀酰亚胺提供了一条绿色的合成方法。The polysuccinimide was produced by polymerization of maleic anhydride and ammonium carbonate in the twin screw extruder reactor.The effects of the catalyst,reaction temperature,material ratio and screw speed on the reaction were investigated.The structures were confirmed by FT-IR,and the polymerization degree of polysuccinimide was determined by limiting viscosity method.The excellent synthesis conditions for polysuccinimide were determined as follows:the material ratio of maleic anhydride,ammonium carbonate and catalyst for 1∶1.5∶0.07,polymerization temperature was 180,195,210℃,screw rotation speed was 60 r/min.Under these conditions,the polymerization degree of the polysuccinimide can reach 276,its monomer conversion is 91.6%.The method has advantages such as available raw materials,simplicity of operates,mild reaction conditions,and pollution-free,which provides a new green strategy for the synthesis of polysuccinimide.
