The rate of solvent evaporation, during the formation of ethylcellulose microcapsules employing polyisobutylene with theophylline ion-exchange resin as the core material, was found to affect the type of coat formed. The predominantly mononucleated mi

The rate of binding of bilirubin by strongly basic anion-exchange resins was determined by the batch method. The rate of uptake of bilirubin from solution was found to follow a second-order rate expression, and the rate constant was dependent upon th
