Abstract: 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.
