氯丁橡胶是最重要的合成橡胶之一.本文综述了氯丁橡胶的填充改性、共混改性、接枝改性及化学改性,介绍了氯丁橡胶改性领域的技术进展和改性氯丁橡胶的主要特性及用途.相比于填充改性、共混改性和接枝改性,氯丁橡胶的化学改性研究相对较少,目前主要集中在氢化改性.相对于氢化,卤化改性不但能够饱和氯丁橡胶中的残余双键,而且可以提高橡胶的硫化活性,改善硫化困难的缺点,因此,优化氯丁胶的氢化改性工艺、探索氯丁橡胶的卤化改性、使其具有更好的综合性能将是今后氯丁橡胶改性的发展方向.

Chloroprene rubber (CR) is one of the most important synthetic rubbers. In this paper,filling modification,blending modification,graft modification and chemical modification of CR are reviewed. Besides,the technology progress in the field of modification of CR and the main characteristics and uses of modified CR are presented. Compared to filling modification,blending modification and graft modification,research on chemical modification is relatively few,mainly focused on hydrogenated modification. With respect to hydrogenated modification,halogenated modification is not only able to saturate residual double bond in chloroprene rubber,but also able to improve the activity of rubber vulcanization. Therefore,optimization of hydrogenated modification and exploration of halogenated modification of CR will be the future direction of modification of chloroprene rubber.
