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.
