“…According to published work, CPE has been blended with many polymers, including polyvinyl chloride (PVC), [1][2][3][4] styreneacrylonitrile (SAN), 5,6 and polyurethane (PU). 7,8 Compared to natural rubber (NR), CPE is relatively expensive, and therefore blending CPE with NR is one of the methods used to reduce the production cost of the final products requiring CPE properties.…”

ABSTRACT:Blends of 80/20 CPE/NR filled with various silica loadings were prepared, and their properties were determined. It was found that cure properties are influenced significantly by the addition of precipitated silica. Scorch time and cure time decrease with increasing silica loading, which could be explained by the thermal history attributed to the shear heating in the blending stage. An increase in crosslink density as a function of silica loading is believed to be caused by a migration of curatives to the NR phase. In terms of phase morphology, with increasing silica loading, the NR dispersed phase size decreases due to the increase in compound viscosity and, thus, the shear stress available for efficient blending. An increase in silica loading also enhances resistance to oil due to the decrease in the NR dispersed phase size associated with the dilution effect, but gives no significant impact on thermal aging resistance. According to the change in damping peak height associated with the shift in T g of the CPE phase, silica appears to preferentially migrate to the CPE phase due to the strong interaction between CPE and silanol groups of the silica surfaces.

“…12 The role of ENR as a compatibilizer for the PVC/ CPE system was also investigated. 13 It was concluded that for blends containing chlorinated polyhydrocarbon with 48% chlorine content or higher, ENR may be used as an effective compatibilizer.…”

A high performance vibration absorber requires a high loss factor behavior over a wide temperature and frequency range. An investigation was carried out to prepare such materials based on poly(vinyl chloride), chlorinated polyethylene, and epoxidized natural rubber ternary blends. The loss factor and damping behavior of several compositions were measured using a viscoelastic spectrometer and a polymerlaminated steel cantilever-beam damping device. Suitable compositions were found to give good mechanical properties and high loss factor over a wide temperature and frequency range. It was also observed that flake-type fillers improve the damping behavior.

“…The incorporation of ELNR into polymer blend including NR has led to positive results. 83,84 The objective of compatibilization of NR with polymers different by their nature and properties, would lead to the elaboration of new functionalized derivatives of NR or its derivatives in which the functionalized units would associate to the NR. So, the development in this field is closely dependent on the progresses noted in the chemistry on NR.…”
