Evaluation of physical and dielectric properties of chloroprene and styrene butadiene rubber blends

摘要

The influence of bis(diisopropyl) thiophosphoryl disulfide, a multifunctional rubber additive, on the curing characteristics and physical properties of polychloroprene rubber and styrene butadiene rubber blends was studied. It is evident from the study that covulcanization of SBR and CR following a two-stage process leads to the development of improved physical properties of the vulcanizates. Dielectric and scanning electron microscopy study supports the occurrence of coherence of the dissimilar rubber blends. (c) 2005 Wiley Periodicals, Inc.
