Abstract

Abstract: The grafted polymer of konjac glucomannan(KGM) with methacryloxylethyl benzyl dimethyl ammonium chloride (KGM-g-DMAE-BC) had been prepared and its antibacterial activity was investigated. The optimum technological conditions were: reaction time 3 h, temperature 70℃, m_KGM:, gram-positive bacteria (Staphylococcus aureus) and fungus (Candida albicans), at becteriostatic rates of 99.99%, 94.26%, 99.99%, respectively.

Key words: konjac glucomannan, quaternary ammonium salt, grafting polymerization, antibacterial activity
