Fund Project:

The crystallization behavior and compatibility of linear low density polyethylene/ethylene-acrylic acid copolymer (13.9mol% AA content), LLDPE/EAA, blends have been studied by means of DMA, DSC, PLM, WAXD and mechanical property measurements. The results show that the noncrystalline phases of LLDPE and EAA are partially compatible, but they can not cocrystallize. Both two components have effects on the crystallization behavior of the blends. LLDPE crystallizes faster than EAA in the blends. However, they do not enter into other's crystal cell. LLDPE and EAA are mechanically compatible. The blends with low EAA content(lower than 40%) show good tensile properties.
