Polyolefin hybrids radical polymerization

Synthesized polymer hybrids based on polyolefins are expected to possess the properties of each polymer segment. Several methodologies for the preparation of polyolefin hybrids have been reported in recent papers [27,28]. In particular, processes such as radical, anionic, cationic polymerizations and... 

The Syntheses of Polyolefin Hybrids via Controlled/Living Radical Polymerization... 

The syntheses, properties and potential applications of polyolefin/non-polyolefin hybrid polymers, Polyolefin Hybrids , via controlled/living radical polymerization have herein been introduced. Polyolefin Hybrids can control the phase stractures, and the surface stmctures on molded polyolefin materials. Polyolefin Hybrids can enhance the physical properties of polyolefins as well as add new properties such as hydrophilicity and antibacterial properties to them. Novel value-added polyolefin materials, Polyolefin Hybrids , have great potential as new value-added materials. 

As mentioned above, the cleavage of Si-Si-bonds in polysilanes upon irradiation with UV-light is very efficient and results in the formation of silicon radicals. These radicals react with olefins to initiate radical polymerizations. Especially the polymerization of methylmethacrylate and styrene with a variety of polysilanes as photoinitiators has been studied in detail [104]. The advantage of this kind of initiation is the possibility to prepare polysilane-polyolefin hybrids [105]. All modifications of radical polymerizations, such as the atom transfer radical polymerization (ATRP), are possible with polysilanes as photoinitiators [106].
