Physical and Morphological Properties of Styrene Butadiene Rubber/Recycled Chloroprene Rubber (SBR/CRr) Blends - The Effects of TOR as a Compatibilizer

Abstract:

Elastomer blends are widely used in rubber products for a variety of reasons, which include improved physical properties, improved service life, easier processing, and reduced production cost [. Butadiene and chloroprene (2-chloro-1,3 butadiene) are related monomers [. Blending of SBR with CR has been done to obtain better crystallisation resistance, better compression set resistance, lower brittleness temperature and enhanced resistance to sunlight deterioration as compared with CR alone. Other important properties, such as oil, heat, flame and ozone resistance, decrease as the amount of SBR increases [. It is possible to improve the phase morphology of SBR/CR blend by incorporating 5±10 phr of a modified copolymer that has segments chemically identical to SBR and CR phases. Addition of halocarbenes to polymers has been reported since a long time; however, available information on the commercial application on such modified polymers is limited [.
