Compatibilization of Polyamide/Polyethylene blend utilizing modified Ethylene Vinyl Alcohol via insitu Nylon grafting

Polymer blending makes it possible to synergistically take advantage of the properties of usually two homopolymers in a single material. But most polymers are incompatible and onmixing, they generally form multiple morphologies. Ethylene-vinyl alcohol (EVOH) having vinyl alcohol units canbe used for grafting nylon chains through polycondensation reactions and then by incorporation of grafted EVOH in polyolefin/nylon blends improved compatibility and stability of the blends can be achieved
