✦ Synopsis

Some resins have been synthesized by reacting quinacetophenone with substituted benzoic acids and furfuraldehyde in the presence of basic catalysts. The resins have been characterized by IR spectra of the characteristic groups. The number average molecular weights of the resins have been evaluated by the conductance method. The solubility and viscosity behaviors of the resin copolymers have been determined. Cu+*, Ni+', Co+*, Mn", and Mg+* chelates have been prepared. The resins were shown to be selective ion-exchange resins for certain metal ions. A batch equilibrium method was used for studying the selectivity of the metal ions. The thermal behavior of the resins has been determined and the values of energy of activation of the resins were computed by using the Freeman-Anderson and Broido methods. The biological assays of some of the resin copolymers were found to be highly sensitive.
