摘要
Abstract
The PE-I.I.D/nano-CaCO3 composites were prepared through melting mixing using a two-roll plasticator. Nonisothermal crystallization behaviors of neat PE-LLD and the composites were studied by means of differential scanning calorimetry. Jeziorny and Mo methods were used to analyze the data. It showed that both Jeziorny and Mo methods could describe this system very well. According to the Jeziorny method, nano-CaCO3 increased the value of To. At the same time, the values of (To--Tp) and t1/2 also increased. This meant that the crystallization rate of PE-LLD was faster than that of PE-LI.D/nano-CaCO3. For a given cooling rate, with increase of the content of nano-CaCO3, the value of crystallization rate decreased at first, then increased. When the content of nano-CaCO3 was 10 %, the value of crystallization rate was the lowest. The value of 77 changed from 1.47 to 2. 13. The conclusion of Mols was the same as that of Jeziorny's. The value of b changed from 0. 75 to 1.22.关键词
