Abstract RU 2634577 C1

FIELD: chemistry.

SUBSTANCE: method comprises dissolving hydroxyethyl cellulose in water in the presence of a crosslinking agent - glutaric acid in an amount of 10-50 wt % of the polymer, drying the resulting film in air at a temperature of 18-25°C and subsequent heat treatment at a temperature of 98-105°C for 180-360 minutes.

EFFECT: simplification and improvement of the process safety, lowering of the heat treatment temperature, longer film stay in the zone of postoperative recovery, and an increase in the anti-spasm effect.
