摘要
用金属钠-硫磺法合成了苯硫醚-乙撑硫醚共聚物。用红外光谱、裂解气相色谱、差热分析和电镜等手段对共聚物进行了表征,并对共聚物的结晶性和热性能进行了初步研究。与聚笨硫醚相比,苯硫醚-乙撑硫醚共聚物的结晶度和耐热性明显降低。
Using sodium, sulfur and P-dichlorobenzene copolymers of phenylene sulfide and ethy-lene sulfide -were synthesized in the solvent hexamethylphosphoramide. The copolymer was characterized by IR, PGC, TEM and SEM. The crystallinity of the copolymer was studied by X-ray diffraction, and the thermostability was also investigated by TGA aad DTG.
