Abstract

The effect of the triblock copolymer poly[styrene-b-(ethylene-co-butylene)-b-styrene](SEBS) on the formation of space charge of immiscible low density polyethylene/polystyrene(LDPE/PS) blends was investigated. The amount of charge accumulated in the 70/30(wt%) LDPE/PS blends decreased when the SEBS content increased up to 10 wt%. For compatibilzed and uncompatibilized blend, morphological observation showed that the addition of SEBS results in the domain size reduction of the dispersed PS phase and a better interfacial adhesion between LDPE and PS phases. The location of SEBS at a domain interface enables charges to migrate from one phase to the other via domain interface and therefore, results in a significant decrease in the amount of space charge for the LDPE/PS blends with SEBS.
