| description | The invention discloses a preparation method of widely-distributed hyperbranched polyethylene and belongs to the field of material chemistry. The method comprises the steps of adding an auxiliary agent in the olefin polymerization process; and jointly adopting the auxiliary agent, a catalyst and a cocatalyst to polymerize ethylene. The molecular weight distribution of the hyperbranched polyethylene can be controlled by using the method disclosed by the invention; meanwhile the decreasing degree of the weight average molecular weight of the polymer is controlled; the obtained copolymer has a broad molecular weight distribution, thereby being beneficial to the performance of the product.
本发明公开了种宽分布超支化聚乙烯的制备方法，属于材料化学领域。所述方法为在烯烃聚合过程中添加种助剂，与催化剂、助催化剂共同使用，使得乙烯聚合。采用本发明的方法可以控制超支化聚乙烯的分子量分布，同时控制聚合物重均分子量的下降程度，所得共聚物具有较宽的分子量分布，这对于产品的性能是非常有利的。 |
