Heat Shrinkable Behaviour of Supramolecular Hydrogen Bonded Maleated Ethylene Propylene Diene Rubber and Maleated High Density Polyethylene Blend

Abstract

Maleated high density polyethylene and maleated ethylene propylene diene rubber ( 50 wt%/50 wt%) was blended in presense of 3-amino-1,2,4-triazole (ATA). The supramolecular hydrogen bonding was characterized by FTIR and dynamic mechanical analysis. The crystallinity of the blend system was studied by XRD and it was observed that supramolecular hydrogen bonding decreases the crystallinity of the blend. The supramolecular hydrogen bonded network improves heat shrinkability of the blend.
