Abstract
Ethylenediaminetetraacetic acid was introduced to glycidyl group attached to acryl ester polymers [ethyl acrylate (EA) : glycidyl methacrylate (GMA) (1 : 1 and 2 : 1), butyl acrylate (BA) : GMA (1 : 1), and GMA homopolymer] to form the polymer containing chelating Ligands as pendant groups. Chelate polymers were obtained by the reaction of the polymers with some transition metal ions. Aqueous solution (0.2%) of Ni-chelate of the polymer derived from EA : GMA (2 : 1) copolymer was found to have 47.6 dyn/cm in surface tension and 11.7dyn/cm in interfacial tension for kerosene. Ni- and Zn- chelates of the polymer derived from BA : GMA (1 : 1) copolymer had excellent emulsifying powers for the mixture of kerosene-water.
