Effect of maleated polyethylene on the crystallization behavior of lldpe/clay nanocomposites

ABSTRACT The crystallization behavior and microstructure of linear low density polyethylene (LLDPE)/modified montmorillonite (20A) composites containing maleic anhydride grafted polyethylene

(MA-g-PE) were investigated by differential scanning calorimetry (DSC), X-ray diffraction (XRD), and transmission electron microscope (TEM). The dispersion of 20A in LLDPE matrix depended

on the amount of MA-g-PE. The degree of super cooling reduced when 20A was introduced into LLDPE with MA-g-PE. The Avrami analysis shows that the nonisothermal crystallization process of the

LLDPE/20A composites followed the Avrami equation with Avrami exponent value in the range of 2.75–3.97. The activation energies calculated by Kissinger method were 986 kJ/mol for LLDPE, 949

kJ/mol for PE-A5MA0, 1445 kJ/mol for PE-A5MA5, and 1581 kJ/mol for PE-A5MA20. The activity of nucleation of PE-A5MA0 was 0.75 but the values of the composites with MA-g-PE were in the range

of 0.37–0.56. These behaviors can be interpreted by the fact that the loading of MA-g-PE in LLDPE/20A composites enhances the dispersion of clay in LLDPE matrix and the good dispersion of

20A affects the degree of super cooling and the nucleation activity of silicate. SIMILAR CONTENT BEING VIEWED BY OTHERS SYNTHESIS OF WATER SOLUBLE IONIC LIQUID COPOLYMERS BASED ON ACRYLAMIDE
