Reactive Blend Systems of PA6/HIPS/PP-g-(GMA-co-St)

Abstract

Abstract: The glycidyl methacrylate(GMA) and styrene(St) multi-monomers melt grafted PP[PP-g-(GMA-co-St)], was used as a reactive compatibilizer of PA6/HIPS blends. The reactive blend system of PA6/HIPS/PP-g-(GMA-co-St) was studied by DSC, SEM and determinations of MFR, torque values and mechanical properties. The results showed that the crystallinity and melting temperature of PA6 were reduced and the interfacial tension and adhesion of the PA6/HIPS were improved in the presence of the PP-g-(GMA-co-St). The micrographs showed the better effect of compatibilization of the PP-g-(GMA-co-St) on the PA6/HIPS blends. When the content of the PP-g-(GMA-co-St) was 10%, the mechanical properties of the PA6/HIPS/PP-g-(GMA-co-St) were much improved; the impact strength of the blend surpassed the pure PA6 and reached the level of the pure HIPS. PA6/HIPS/ PP-g-(GMA-co-St) plastics alloy with the proportionate and good mechanical properties has been obtained by the reactive blend.
