摘要
本文研究了CPVC/AS和CPVC/MBS两种共混物的挤出胀大行为。结果表明,共混物的挤出胀大比在不同温度下均随表观切变速率的增大而增大,并且对温度有不同的依赖性;共混物的胀大行为并非完全是弹性响应,还与非弹性因素有关。
Extrudate swell behaviourof CPVC/AS and CPVC/MBS blends was studied. The results demonstrated that under various tempera tures the swelling ratio of every blend increased as the apparent shear rate increased. There existed different relationships between swelling ratios and temperatures. Not only the elastic element, but nonelastic element had a direct bearing on the swelling ratio.
