A STUDY ON PVC LLDPE BLENDS WITH SOLID-STATE-CHLORINATED POLYETHYLENEAS COMPATIBILIZER/

Chlorinated polyethylene (CPE) prepared by solid-state chlorination wa s used as a compatibilizer for poly(vinyl chloride) (PVC)/linear low-d ensity polyethylene (LLDPE) blends. Effects of CPE molecular structure on stress-strain behaviors, dynamic mechanical properties, and morpho logies of PVC/LLDPE blends were studied by using SEM, TEM, DMA, and te sting mechanical properties. The results showed that the compatibility of PVC/LLDPE blends was improved with the addition of CPE. Also, adhe sion strength between the two phases and mechanical properties of the blends were increased. (C) 1997 John Wiley & Sons, Inc.
