磺化功能改性聚乙烯研究进展

Advances in functionalization of polyethylene by sulfonation

磺化是功能改性聚乙烯(PE)的重要手段,可有效改善其化学极性、刚性和热稳定性。主要综述了PE磺化过程中化学结构和物理性能的变化,探讨了反应机理,指出今后磺化PE的研究和应用方向。

As one of the most important functionalization methods,sulfonation was effective in improving chemical polarity,stiffness and thermal stability of polyethylene(PE).In this paper,research advances are reviewed on the structural evolution and performance modification of sulfonated PE as well as the sulfonation mechanisms,based on which the prospective research and application of sulfonated PE are discussed.
