Polyolefins, which include various types of polyethylene and polypropylene and, to a much lesser extent, higher polyolefins and olefin copolymers, have been the dominant group of polymersfor years. Thisis due to both the significant development of their production technology, which has become environmentally friendly over the years, and their diverse physicochemical properties. Additionally, the properties of polyolefins, and therefore their areas of application, can be significantly extended by copolymerizaton of olefins with other vinyl compounds, changing their topology and microstructure as well as by modifying their surface or making composite materials. This review reports the state of the art in the field of copolymerization of olefins with alkenylsilsesquioxanes, polar monomers and cycloolefins, which give the resulting materials favorable characteristics in terms of thermal resistance, adhesion and others properties. The next subjects of consideration were the synthesis of multiblock olefin copolymers by chain shuttling polymerization and the synthesis of telechelic polyolefins using, among others, anionic and coordination polymerization. Finally, the modification of polyolefins towards obtaining antibacterial materials and their use in the field of medicine and the packaging industry were discussed.
