Anion-exchange resin beads in the theophylline form were prepared and coated with
paraffin or encapsulated with ethylcellulose by various methods; one of these products was …

Phase diagrams were prepared to indicate the region of microcapsule formation for the following
system: cellulose acetate phthalate, light mineral oil, acetone: 95% ethanol solvent, and …

Stereological estimates of the numbers of Purkinje cell nucleoli in human cerebellar cortex
have been obtained from systematic random samples of tissue by using the fractionator. The …

A method is presented for encapsulating high molecular weight biological materials such as
viral antigen, concanavalin A, and other proteins with cellulose acetate phthalate. The …

The influence of the viscosity of the internal and external phases and the interfacial tension
between the two phases, in the emulsion type of microencapsulation system was investigated…

A method for controlling microsphere particle size by regulating the ratio of polymer to
solvent concentration and volume fraction, for an emulsion-solvent removal type of …

Ion-exchange resin beads in the benzoate form were coated by several microencapsulation
techniques to alter and improve characteristics, especially the control of drug release, of this …

Ion‐exchange resin beads were coated with various waxes to improve and control their
release. The in vitro release rates of benzoate ions from the coated resin beads were then …

Controlled release homogeneous matrix microspheres containing acetylsalicylic acid (ASA)
were prepared by a simple mechanical process using Eudragit® RS100 as the matrix …

Organic anions with similar properties, but different molecular weights, were bound to anion‐exchange
resins with different cross‐linking. It was found that the capacity of the ion‐…
