“…It was noted that the homopolymer arises partly from thermal degradation of the polyamide substrates. 92,93 An interesting application of the Mn 2 (CO) 10 -based photoinitiating system is the grafting of low molecular weight polytetrafluoroethylene bearing terminal Mn(CO) 5 groups onto polystyrene-co-poly(methyl methacrylate) (Scheme 16). In the case of photoinitiated polymerization of tetrafluoroethylene in the presence of the copolymer, the polymeric radicals undergo both addition and substitution reactions with aromatic nuclei in the copolymer, so that the final graft copolymer carries short polytetrafluoroethylene chains with Mn(CO) 5 end groups.…”

“…The membrane was immersed in an aqueous monomer solution with concentrations of 1, 5, and 10 wt% for different periods of time, and placed into a Pyrex glass tube closed with a rubber stopper and replaced with nitrogen. Graft polymerization was carried out under UV irradiation at a distance of 12.5 cm for 1 h at 35 ± C. The grafted membrane was rinsed with hot water (70 ± C) for at least 48 h to remove the homopolymer [17], and then dried in vacuum at 50 ± C for 24 h.…”

“…To realize the graft polymerization of vinyl monomers onto PU, different methods such as plasma treatment [13],°-ray irradiation [14], ozone oxidization pretreatment [15], cerium(IV) ions, or transition metal activation [16,17] were employed. Among them,°-ray irradiation and plasma treatment were widely used.…”

“…In order to decrease protein adsorption which, in its turn, is related to subsequent bacterial adhesion [6], it is important to enhance the hydrophilicity of polymeric biomaterials. One of the most efficient means for that is incorporating various covalently bound substituents with polar (ionic) functional groups in the polymer chains [7][8][9].…”
