A Study on the Antimicrobial Activity of Allylamine Polymers(II)

Allylamine계 항균제의 합성 및 그 항균성에 관한 연구(II)

The antimicrobial activities of the copolymer of N,N'-dimethyl- N,N'-diallyl ammonium chloride(DMDAAC) and diallyl amino(DA) were investigated. The copolymer of DMDAAC and DA was prepared by free radical Polymerization through an intra-intermolecular propagation mechanism ie, cyclopolymerization. The copolymer was, then, reacted with cyanuric chloride for reactivity with hydroxyl group of cellulose. Cotton fabrics were finished by synthesized polymer, and their antimicrobial activities and fastness to launderings were tested. Dichlorotriazinyl DMDAAC-DA copolymer has MIC value of 1ppm against S. aureus and 10ppm against K pneumoniae. The antimicrobial fastness of the finished cotton to launderings were good enough to show colony reduction above 70% against S. aureus and K pneumoniae after 50 repeated laundering in anionic commercial detergent. Optimum treatment concentrations of the polymer were 0.5% in cold pad-batch method, and 0.1% in pad-dry method.
