Non-isothermal melt crystallization kinetics for ethylene–acrylic acid copolymers and ethylene–methyl acrylate–acrylic acid terpolymers

Non-isothermal melt crystallization kinetics and subsequent melting behavior for four different grades of ethylene–acrylic 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.
