[The study of quality characteristics of the hydrogel ointments and films based on copolymers divinyl esters of diethylene glycol].

The possibility of using a hydrogel based on divinyl ether co- and terpolymer of diethylene glycol as the backbone polymer for incorporating water-soluble medicinal substances was examined. The character of the influence of emulsifiers, plasticizers, high-boiling liquids and bioactive substances is defined within the changes of physical-chemical properties of obtained hydrogels. The obtained polyelectrolyte hydrogels by their homogeneity, dehydration and rheological characteristics may be of concern in function of matrices to create external prolonged-action dosage forms.
