| 摘 要： | 本文研究了用稀土催化剂聚合得到的聚乙烯(稀土聚乙烯)的结构及性能。发现初生聚乙烯粉末具有条状形态结构,其支化度、结晶度及晶粒尺寸均与低压聚乙烯相似,但其熔点和特性粘数较高。用各种物理方法初步证明,稀土聚乙烯熔点较高的原因可能与其具有伸展链结晶结构有关。

| Abstract: | The physical properties of polyethylene obtained with rare earth catalyst have been studied by various methods. The morphology of nascent polymer powder shows strip structure by scanning electron microscope. Branched content, crystallinity and crystallite size are similar to those of high density polyethylene. The melting point of polyethylene powder and its molecular weight ate higher than those of high density polyethylene. The experimental results indicate that the polyethylene synthesized with rare earth cata-lyst shows characteristics of extended molecular chain. |
