Study on Copolymerization of Acrylamide With Styrene Initiated by Methyl Ethyl Ketone and Its Derivatives in Comparison With Conventional Radical Initiator

Effective antibacterial modification of poly-(ethylene terephthalate) (PET) was achieved by forming a surface thermoplastic semi-interpenetrating network of polyacrylamide (PAM) and PET, followed by converting the immobilized amides to N-halamine. The regenerability of N-halamine on PAM-modified PET was significantly influenced by the cross-linkers used to form the network. Through Fourier transform infrared spectroscopy and nitrogen content analysis of the materials for up to 29 regeneration cycles, it was found that breaking down of the PAM network in chlorination accounted for the loss of regenerability. The relationship between antibacterial efficacy and N-halamine concentration was also studied. Compared with N,N 0 -methylenebisacrylamide and 2-ethyleneglycol diacrylate, cross-linker divinylbenzene can generate more durable PAM network. After 29 regeneration cycles, the PAM-divinylbenzene network-modified PET was still able to provide 100% reduction of healthcareassociated methicillin-resistant Staphylococcus aureus in 20 min contact.

Acrylamide (AAm) was found to polymerize in a solution of poly(N-isopropylacrylamide) (PNIPAAm) in water at around its lower critical solution temperature (LCST) (328C) without any initiators. This phenomenon was specifically observed in aqueous solutions of the polymers having LCST such as PNIPAAm and poly(methylvinylether) (PMVE). AAm polymerized only when PNIPAAm and AAm were dissolved in water below LCST of PNIPAAm and then the solution was warmed up to the polymerization temperature (408C). On the other hand, the polymerization of AAm did not proceed when AAm was added into aqueous PNIPAAm solution during and after the phase separation above 328C. Furthermore the polymerizability of AAm was remarkably affected by the concentration and molecular weight of the PNIPAAm additives. Under the condition of lower PNIPAAm concentration (0.30 mol/L), the increase in the molecular weight of PNIPAAm considerably increased the molecular weight of the resulting PAAm but decreased the yield of PAAm. Under the condition of higher PNIPAAm concentration (0.60 mol/L) the polymerizability was not so affected by the molecular weight of PNIPAAm, while the molecular weight of PAAm formed by using higher molecular weight PNIPAAm was higher than those of PAAm formed by using lower molecular weight PNIPAAm. Moreover, the molecular weight of PAAm formed by the PNIPAAm induced polymerization of AAm was much higher than that of the polymer obtained by the radical polymerization using AIBN in THF or VA-061 in water.
