Abstract
Freeze-dried polymer latices, which can be reconstituted in water to give aqueous polymer dispersions having high polymer solids content, are described. The reconstituted polymer dispersions are useful in preparing sustained-release drug formulations, particularly of water-soluble drugs, by the wet granulation method without over wetting.
