Polyethyleneoxide grafting

Commercial hybrid grafts include structures in which organic polymers are grafted onto a polysiloxane chain, such as polyethyleneoxide graft polydimethyl-siloxane surfactants, or structures in which alkoxysilanes are grafted onto organic polymers such as crosslinkable polyethylenes. 

Polymer grafting can be used to alter chemical and physical properties of a homopolymer. For example, Sawhney and Hubbell [18] grafted polyethyleneoxide to poly L-lysine to enhance biocompatibility of polylysine and improve the polylysine-alginate capsules. Stevenson and Sefton [19] modified alginate by grafting it with hydroxyalkyl methacrylate, again to improve the biocompatibility and to allow for polymerization by means of y-irradiation. Covalently modified (co)-polymers have not been evaluated in this study.
