Abstract
Reactive monomer, glycidyl methacrylate (GMA), was grafted onto low density polyethylene (LDPE) using peroxide and then reactive blend with nylon-6 was rallied out by corotating twin screw extruder. Grafting of GMA was identified using FT-IR. Graft ratio or GMA increased with reaction temperature, peroxide concentration and styrene comonomer concentration. It is observed that tensile elongation and tensile strength or LDPE-g-GMA/nylon-6 blend were higher than those of LDPE/nylon-6 blend. Morphology of blend was analyzed using SEM.
