摘要：
Non-isothermal melt crystallization kinetics and subsequent melting behavior for four different grades of ethyleneacrylic acid copolymer and three different grades of ethylene-methyl acrylate-acrylic acid terpolymer was investigated by differential scanning calorimetry technique. The non-isothermal melt crystallization data were analyzed based on the Ozawa and Ziabicki macrokinetic models. The effective energy barriers describing non-isothermal melt crystallization process for these resins were determined based on the differential iso-conversional method of Friedman. The amount of non-crystallizable, intra-molecular defects had substantial effects on the non-isothermal melt crystallization kinetics and subsequent melting behavior. (C) 2003 Elsevier Ltd.
