摘要：
Blend prepared by melt mixing of thermoplastic elastomer has gained considerable attention in recent years. The present study deals with the measurement of heat shrinkability of the blends of the low-density polyethylene (LDPE) and carboxylated nitrile rubber (XNBR). Two samples have been prepared for this purpose. In the first sample, LDPE is blended with XNBR, while in the second sample, glycidyl acrylate (GA) grafted LDPE is blended with XNBR. It is revealed that interchain crosslinking in the grafted LDPE and XNBR improves the heat shrinkability. Here, crosslinked point between rubber and plastic molecules serve as memory point during the recovery process, which is responsible for the improvement of heat shrinkability. High temperature performance of the sample (as far as shrinkability is concerned) depends on interchain crosslinking. The mechanism of interchain crosslinking reaction is confirmed by infrared (IR) spectroscopic analysis. (C) 2000 Elsevier Science B.V. All rights reserved.
