Abstract

Blends prepared by melt mixing of thermoplastic materials/elastomers have gained considerable attention in recent years from the viewpoint of heat shrinkability. The present study deals with the measurement of heat shrinkability of the blends of grafted ethylene-propylene polymer and polyurethane elastomer. The used grafting materials are acrylic acid, vinyltriacetoxysilane, and glycidyl acrylate. Interchain crosslinking between grafted ethylene-propylene polymer and polyurethane elastomer improves the heat shrinkability. The high temperature performance of the sample is dependent on interchain crosslinking. From torque rheometry it was observed that the maximum amount of interchain crosslinking occurred in the sample containing glycidyl acrylate as grafting material. The probable interaction between rubber and plastic phase was confirmed by IR spectroscopy.
