摘要：

Cationic polystyrene latex was coated with uniform layers of yttrium basic carbonate by aging at elevated temperatures dispersions of the polymer colloid in the presence of aqueous solutions of yttrium nitrate, urea, and polyvinylpyrrolidone. The thickness and morphology of the deposited layers could be altered by suitably adjusting the reactant concentrations, aging time, and temperature. A mechanism for the formation of the coating shell is suggested. © 1990.
