Effect of blending procedure on morphology of LDPE/LLDPE/PA blends

Polymer blending is a convenient and attractive technique for obtaining new polymeric materials. Blends of polyethylene (PE) with polyamide-6 (PA) may lead to synergic combinationof the typical properties of PE (low cost, process-ability, resilience, and moisture insensitivity) with those of PA, i.e.rigidity, thermal stability, and barrier properties to oxygen and solvents. The synergistic properties are reachable as long as the blends are appropriately compatibilized [1-4].
