Abstract

The compatibilizing effects of the compatibilizer, ethylene-acrylic acid random copolymer(EAA), on linear low density polyethylene (LLDPE)/poly (ethylene oxide) (PEO) blends and the mechanism of compatibilization of the blends have been studied. Morphology and microstructures as characterized by SEM, DMA, DSC and IR show that EAA can act as an effective compatibilizer, and the mechanism of compatibilization is due to the compatibillity of amorphous phases between EAA and LLDPE, and intermolecular interaction between the carboxylic groups in EAA and the ethereal oxygens in PEO.
