Synthesis of Benzisothiazolinone Grafted Acrylate Zinc Resin and Its Antibacterial Activity

Benzisothiazolinone grafted acrylate zinc resin which has the similar antifouling structure to acrylate TBT resin was synthesized.Benzisothiazolinone was modified by grafting a carboxyl group from maleic anhydeide and added it to acrylic resin as a side-chain in order to obtain benzisothiazolinone grafted acrylate zinc resin.Then benzisothiazolinone grafted acrylate zinc resin was characterized by FI-TR and ¹H-NMR.Besides, antibacterial experiment by Vibrio sp.and Pseudoalteromonas sp.show that benzisothiazolinone grafted acrylate zinc resin has excellent antibacterial activity.
