通过差示扫描量热仪(DSC)研究了乙烯-辛烯共聚物/淀粉共混体系的非等温结晶动力学,用Jeziorny和Ozawa方程描述了结晶动力学过程.共混物的结晶温度和结晶焓强烈依赖于淀粉含量和冷却速率.结果表明,随着冷却速率的增加,每个试样的结晶放热曲线均变宽,并向低温区移动.当温度一定高时,所有试样均具有较快的结晶速率. Jeniorzy方程可以较好地描述POE/淀粉共混物的非等温结晶模式,而Ozawa方程对于POE/淀粉共混体系不太适合. The non-isothermal crystallization kinetics of ethylene-octene copolymer / starch blends was studied by differential scanning calorimetry (DSC), and the crystallization kinetics was described by Jeziorny and Ozawa equations. The crystallization temperature and crystallization The enthalpy is strongly dependent on the starch content and the cooling rate. The results show that the crystallization exothermic curve of each sample becomes wider as the cooling rate increases, and moves toward the low temperature region. When the temperature is high, all the samples have Faster crystallization rate Jeniorzy equation can describe the non-isothermal crystallization mode of POE / starch blend better, while Ozawa equation is not suitable for POE / starch blend system.
