Polymers Derived from 4-Substituted Salicylic Acids as Antifungal Agents

Abstract
4-Amino-, chloro- and bromo-substituted salicylic acid-formaldehyde polymers and their metal chelates were screened for antifungal activity. Various copolymers prepared from 4-chloro-(bromo)salicylic acid, formaldehyde and other comonomers were also screened for antifungal activity. All these polymers, copolymers and polychelates were active against several fungi. Their fungicidal activities were compared with those of the corresponding monomers and monomeric chelates.
