摘要
本文着重研究了PVC／NBR－40热塑性弹性体对酚醛泡沫塑料的增韧改性。采用差示扫描量热法（DSC），考察了共混体系的固化反应特性。结果表明，固化体系与其他体系在发泡成型中相互独立。PVC／NBR－40热塑性弹性体对酚醛泡沫塑料有显著的增韧效果。
In this paper, enhancement of the toughness of phenolic foams with PVC/NBR-40 thermoplastic elastomer have been emphatically studied. The Curing properties of the blend systems have been studied by DSC. The result indicated that curing system and other systems were independence during the foaming process. The phenolic foams' toughness have been improved marked when using PVC/NBR - 40 thermoplastic elastomer.
