Abstract

The features of chlorosulfonated polyethylene thermolysis were studied and it was found that free radicals formed after the simultaneous homolytic cleavage of carbon–sulfur and sulfur–chlorine bonds not only react with each other (recombination or disproportionation), but also abstract a hydrogen atom from the macromolecule of polyethylene or ethylene–propylene rubber, providing crosslinking of macromolecules, accompanied by an increase in the strength properties of composites based thereon.

氯磺化聚乙烯的热降解特征

摘要研究了氯磺化聚乙烯热解的特点，发现碳-硫键和硫-氯键同时均聚裂解后形成的自由基不仅会相互反应（重组或歧化），还会从聚乙烯或乙烯-丙烯橡胶的大分子中抽取一个氢原子，从而使大分子交联，并提高了以其为基础的复合材料的强度性能。

期刊介绍： Russian Journal of Applied Chemistry (Zhurnal prikladnoi khimii) was founded in 1928. It covers all application problems of modern chemistry, including the structure of inorganic and organic compounds, kinetics and mechanisms of chemical reactions, problems of chemical processes and apparatus, borderline problems of chemistry, and applied research.
