The effect of compatibillization in presence of maleic acid on moisture barrier and physical properties of Poly(vinyl alcohol) (PVA)/linear low-density polyethylene (LLDPE) blends |
초록 |
Blends of poly(vinyl alcohol) (PVA)/linear low-density polyethylene (LLDPE) were prepared by conventional thermoplastic processing technique. The PVA and LLDPE were blended to give the following blend ratios(wt%): 5/95, 10/90 and 20/80. The effect of maleic acid via in situ cross-linking on processability, component interaction, thermal stability, tensile properties, morphology, hygroscopic degree and moisture barrier of PVA/LLDPE blends was investigated in this research. The results indicated that the presence of maleic acid increases moisture barrier properties of PVA/LLDPE blends. The formation of cross-linking was confirmed by Fourier transform infrared analysis and depression of melting points of PVA and LLDPE in the blends. The thermal stability, moisture barrier properties and mechanical properties such as tensile strength and elongation-at break of the LLDPE/PVA blends also improved in the presence of maleic acid. Evidence for greater compatibility between PVA and LLDPE was confirmed by scanning electron microscopy micrographs. |
