Dynamically vulcanized acrylonitrile–butadiene–styrene terpolymer/nitrile butadiene rubber blends compatibilized by chlorinated polyethylene

Abstract

Thermoplastic vulcanizates (TPVs) based on acrylonitrile–butadiene–styrene (ABS)/nitrile butadiene rubber (NBR) blends were prepared by dynamic vulcanization and then compatibilized by chlorinated polyethylene (CM). The effects of CM compatibilizer on the mechanical properties, Mullins effect, and morphological and dynamic mechanical properties of the TPVs were investigated systematically. Experimental results indicated that CM had an excellent compatibilization effect on the dynamically vulcanized ABS/NBR TPVs. Mullins effect results showed that the compatibilized ABS/NBR TPV had relatively lower internal friction loss than the ABS/NBR TPV, indicating the improvement of elasticity. Morphology studies showed that the fracture surfaces of ABS/CM/NBR TPVs were relatively smoother, indicating the improved elastic reversibility. DMA studies showed that the glass to rubber transition temperatures of ABS and NBR phases were slightly shifted toward each other with the incorporation of CM compatibilizer, which indicates the improvement of the compatibility. © 2014 Wiley Periodicals, Inc.

Synthesis of silane‐grafted ethylene vinyl acetate copolymer and its application to compatibilize the blend of ethylene‐propylene‐diene copolymer and silicone rubber

“…b. Wei and Hua have reported on a similar morphology of ABS/NBR blends compatibilized by CM . The improved interface interaction arises from the incorporation of compatibilizer, the good compatibility of EPDM and EVA, and in addition from hydrogen‐bond interaction between hydroxysilane and silicone rubber reducing the interfacial tension and improving the adhesion between the rubber constituent phases .…”

Preparation and applications of electrochemical chemosensors based on carbon-nanomaterial-modified molecularly imprinted polymers

“…Wei et al prepared MIP, using ampicillin as the template, as well as MAA, EGDMA, and AIBN. 97 AuNPs were dropped on a Pt electrode. MWCNT–COOH was added on AuNP-modified electrodes, followed by the dropcasting of a MIP solution on AuNPs/MWCNTs-modified electrode to develop an ampicillin-imprinted sensor.…”

Synergistic Effect of Copper Sulfate and Tetramethylthiuram Monosulfide Induced Metal‐Coordination Cross‐Linking in Nitrile–Butadiene Rubber

“…A large number of nitrile groups in NBR could provide high-intensity cross-linking in metal-coordination interaction of polymers; moreover, due to the high polarity of nitrile groups, NBR tends to blend with metal salt. [27,28] Copper sulfate (CuSO 4 ) acts not only as a coordination cross-linking ingredient, but also as reinforcing fillers in the building of NBR/CuSO 4 coordinated cross-linking system by a simple blending. [6,13,29,30] However, the inorganic metal salt particles usually could not be homogeneously dispersed in the organic polymeric matrix, leading to the poor interfacial compatibility and the low cross-linking density; these shortcomings and drawbacks of metal-coordination cross-linking lead to the lack of resiliency, thermal stability, and chemical resistance of rubber, which cannot satisfy the application of actual engineering.…”
