CROSSLINKING AND COMPATIBILIZATION IN BLENDS OF POLYSTYRENE AND POLYETHYLENE*
This paper investigated the influences of butadiene rubber (BR) and dicumylperoxide (DCP) on thermal and rheological behaviour
morphology and mechanical proper-ties of PS/LLDPE/SBS blend. Addition of DCP alone was found to decrease the mechanicalproperties of PS/LLDPE/SBS blend due to the decomposition of PS. When BR was addedtogether with DCP
it is found that the co-crosslinking of BR
SBS and PE takes place
and the decomposition of PS is reduced simultaneously because of the consumption of thefree radicals in the crosslinking process.Synergism was thus realised which resulted in the improvement of the ductility of blend.
