The effects of physical and morphological properties of styrene butadiene rubber/virgin chloroprene rubber blends (SBR/CRv) and styrene butadiene rubber/recycled chloroprene rubber blends (SBR/CRr) were investigated. Both SBR/CRv blends and SBR/CRr blends were prepared using two roll mill at room temperature with blend ratios 95/5, 85/15, 75/25, 65/35 and 50/50. The range size of CRr used in this study was 0.3 0.7 mm. The SBR/CRr blends shows higher value of hardness and crosslink density compared to SBR/CRv blends at all blend ratios. The scanning electron microscopy (SEM) of tensile fracture surface of SBR/CRr blends at 15 blend ratio illustrated a better adhesion and dispersion of CRr with SBR matrix compared with SBR/CRv blends.

Styrene Butadiene

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 [.
