摘要: AbstractA latex which is a polymerized and cross-linked product of hydroxyendblocked polydimethylsiloxane an alkoxysilane has been evaluated as controlled release tablet film coating system. With adequate reinforcement colloidal silica, the silicone elastomer formed solid elastomeric free films upon drying. Polyethylene glycols different molecular weights were incorporated in system to enhance permeability hydrophilic ionic species. Free derived from three-component dispersions by various physical chemical methods with respect their suitability aqueous
