Nonisothermal Crystallization Behavior of In-Situ Formed Polyethylene/Montmorillonite (PE/MMT) Nanocomposites Through Ethylene Copolym-erization

Abstract

PE/MMT nanocomposites containing different amount of MMT were measured for isothermal crystallization. The combination of Ozawa equation and Avrami equation was found applicable in explaining the crystallization behavior of the nanocomposites. In certain range of MMT loadings, MMT particles played the role of nucleating agents that pro- moted the crystallization rate of the polymer matrix, thus making the adjustment of the crystallinity of PE nanocomposites flexible and convenient.
