液-固相本体反应制备氯磺化聚乙烯及性能

本文研究了磺酰氯作为反应试剂,采用液-固本体法制备氯磺化聚乙烯的可行性。对产物进行红外分析,发现经过氯化和磺化后在1160.40cm_-1处有明显的吸收峰,可认为该峰是-SO₂Cl₂的贡献；通过测定产物在多元醇硫化体系下的硫化曲线,并与CPE进行比较发现其焦烧时间明显短于CPE,这也间接验证了该方法制备氯磺化聚乙烯(CSM)的可行性。另外,对产物的力学性能进行了初步探索,与相同氯含量的CPE相比,其性能显著提高。;This paper studied the probability to synthesize the CSM via the liquid-solid bulk polymerization using sulfonyl chloride . Through the infrared spectrum analysis, it was found that there is a obvious absorption peak at 1160.40cm_-1 after chlorination and sulfonation. It can be considered that the peak is the contribution of –SO₂Cl₂; By measuring the product’s vulcanization curve in the polyols vulcanization system,we found that its scorch time is significantly shorter than that of CPE, which also indirectly proved the feasibility of this method to prepare CSM. In addition, we carried out a preliminary study on its mechanical properties and found that its performance improved significantly compared with the same chlorine content of CPE
