Effects of HDPE-g-MAH and POE-g-MAH on the properties of PE100/PA6 blend

PE100/PA6 blend alloys were prepared via melting extrusion with high-density polyethylene grafted with maleic anhydride(HDPE-g-MAH) and ethylene-octene copolymer grafted with maleic anhydride(POE-g-MAH) as two compatibilizers separately.The effects of two compatibilizer contents on mechanical properties,thermal properties,and microstructure of the blends were investigated.The results showed that both compatibilizer addition caused reactive compatibilization,compared to POE-g-MAH,HDPE-g-MAH is more beneficial to the crystalline,comprehensive performance,more suitable for PE100/PA6 in heat resistant modification.
