摘要：
The polyethylene nanocomposites were prepared by in-situ polymerization method using the Ziegler-Natta catalyst supported on the organoclay/MgCl2 bisupport in the presence of AlEt3 as the cocatalyst. The organoclay used is commercial Claytone APA. With XRD and TEM, the exfoliation of the layered silicate gallery of Claytone APA was confirmed. For the resulting polyethylene nanocomposites, the melting and crystallization behaviors were investigated by DSC, and their thermal property was examined in thermal oxidation condition.
