摘　　要：采用加入单炔基的苯乙炔共聚;低温下长时间的预聚来控制间二乙炔基苯的聚合放热。并用红外光谱对聚合物的固化物进行了结构表征。结果表明:加入30%的苯乙炔能使间二乙炔基苯的聚合反应焓从2013J/g 降为1050J/g;经过预聚,间二乙炔基苯的反应焓降为452.6J/g;间二乙炔基苯发生均聚或与苯乙炔发生共聚,炔键打开生成大量的双键,形成苯环或顺式共轭多烯结构。The prepolymer polyarylacetylene was synthesized from meta-diethynylbenzene and pheny- lacetylene through homopolymerization and copolymerization.Methods of reducing △H of polymerization were investi- gated.△H of meta-diethynylhenzene polymerization was reduced to 1050J/g by adding 30% phenylacetylene and to 452.6J/g by prepolymerization at low temperature from 2013J/g.The structure of cured resin was studied.Through homopolymerization or copolymerization,acetylene bonds were opened,and phenyl and comjugated cis-polyene struc- ture were formed.
