Influence of styrene–ethylene–butylene–styrene on the properties of acrylonitrile butadiene styrene–high-impact polystyrene blends

Abstract

A binary blend (ABS-HIPS 50% wt) was prepared on a twin-screw extruder at 190-210 ºC. The different properties were then analyzed using tensile strength and impact tests, melt flow index (MFI), thermogravimetric analysis (TGA), and

Theoretical and Experimental Investigations of Shape Memory Characteristics of Miscible Rubber-Wax Blends

“…that are characteristic of polymer blends. [30][31][32][33][34] In the current manuscript, we demonstrate a simple mechanism of developing SMPs via blending of two components-rubber and wax. Specifically, we predict the shape memory characteristics of rubber-wax system via simulations and subsequently, perform experiments to validate our predictions, qualitatively.…”

Enhanced mechanical properties of recycled blends acrylonitrile–butadiene–styrene/high–impact polystyrene from waste electrical and electronic equipment using compatibilizers and virgin polymers

“…The increase in ductility of ABS/HIPS blends from WEEE containing the compatibilizer SBS has also been verified in others studies. 8,25,27,28 Block copolymers such as SBS, SEBS, and SEB are recognized for acting as compatibilizers in immiscible polymer blends since a specific segment of the copolymer interacts with the matrix, while another segment Note: The numbers are marked in bold to highlight the lowest values of tensile strength (σ) and Young's modulus (E) as well as the highest values of elongation at break (ε) and impact resistance (IR) for alone components (ABS and HIPS) and their blends (HrA and ArH) using the compatibilizers C1 and C2.…”

“…24 For ABS/HIPS blends are increasingly used the copolymers styrene-acrylonitrile (SAN), styrene-butadiene-rubber (SBR), styrene-butadiene-styrene (SBS) 25,26 and styrene-ethylene-butylenestyrene (SEBS). 27,28 Other way for recovery of properties in recycled ABS/HIPS blends is the incorporation of virgin polymers ABS or HIPS, which can adjust the blend composition as well as to decrease the effects of properties loss caused by degradation during the lifetime of the material. 14,15,29 Based on these considerations, the aim of the present study was to evaluate the influence of the incorporation of compatibilizers SEBS and SBS as well as of virgin polymers ABS and HIPS on the morphology and mechanical properties of recycled ABS/HIPS blends in order to define suitable and enhanced conditions for their mechanical recycling.…”
