功能化聚烯烃材料的制备与性质研究

The Synthesis of Functionalized Polyolefin Materials and Research on Material Properties

聚烯烃年产量巨大、用途广泛,但是其最大的缺点之一是其非极性。向非极性聚烯烃中引入少量的极性官能团可以极大地改善其性质、拓宽其用途、提高其商业价值。因此,功能化聚烯烃材料受到了学术界和工业界一致的关注。本文将主要基于作者课题组的相关工作,介绍其在催化剂结构创新、极性单体的选择、聚合新技术等方面的研究进展。在此基础之上,制备了一系列带有极性基团的聚烯烃材料,并系统地研究了这些功能化聚烯烃材料的性质。

Polyolefins have huge annual production and wide applications. However, one of their biggest limitations is their nonpolar nature. The introduction of small amounts of polar functional groups into non-functionalized polyolefins can greatly improve many properties, broaden their applications and increase their business values. Therefore, functionalized polyolefins are of growing interest scientifically and industrially. This account focuses on the research works from our research group and describes the following topics: the development of new catalyst systems, the selection of polar monomers and the new polymerization techniques. Subsequently, we describe the synthesis of a series of polyolefins with incorporation of some polar groups, as well as the studies of the properties of polar functionalized polyolefins materials.
