采用合成聚苯硫醚的方法,研究了2,5-双(氯甲基)噻吩(DCMT)、间-二氯甲基苯(DCMB)和硫化物的共聚反应,对聚合物做了红外光谱分析测定,计算并分析了含硫量与DCMT和DCMB的摩尔组成的关系以及成膜性能试验.
The copolymerization of 2,5-bis (chloromethyl) thiophene (DCMT), m-dichloromethylbenzene (DCMB) and sulfide was studied by the method of synthesizing polyphenylene sulfide. The infrared spectra The relationship between sulfur content and the molar compositions of DCMT and DCMB as well as the film-forming properties were calculated and analyzed.
