Thermoplastic copolyether ester elastomer toughened polycarbonate blends - 3. Microhardness and abrasion resistance of the blends

摘要

Blends of polycarbonate (PC) and thermoplastic copolyether ester elastomer (COPE) were prepared by melt blending using a single screw extruder in different weight percentages. Vickers microhardness and abrasion resistance measurements were carried out to study the effect of COPE composition on PC/COPE blends. It is observed that both microhardness and the abrasion resistance decrease with increase in the COPE weight percentage in the blends. The change in morphology to co-continuous phase from droplets as the COPE content reaches 20 wt% has a significant effect on the properties. (C) 2004 Elsevier Ltd. All rights reserved.
