Abstract

The melt blends of recycled polycarbonate and recycled poly(acrylonitrile-butadiene-styrene) were performed by using a novel vane extruder. The morphology, mechanical, and thermal properties of the RPC/RABS blends in the whole composition range were investigated. When the concentration of RABS was 20 wt%, the blend presented the best comprehensive mechanical properties, especially for the impact strength which was significantly improved compared with RPC and RABS individuals. The blend with 90 wt% RABS also presents better mechanical properties compared with the adjacent blending ratio. With the increase of RABS concentration in blends, Tg of the RABS phase decreases slightly, but Tg of the RPC phase increases. The DSC and SEM results indicate that RPC are partial miscible with RABS.
