摘要
Recycling of used PVC needs a careful characterization of PVC waste. The analysis of the scrap, especially with respect to the thermal stability and the molecular weight, is useful before reprocessing. Additional stabilization of used PVC can be done by up to 10 wt% fillers, e.g. chalk, which does not change the mechanical properties. A literature survey on the proposed concepts and methods for material and chemical recycling of PVC is given. (C) 2002 Published by Elsevier Science Ltd.
