<p>A process for producing a medical coating-type liquid phase release polymer developed for a novel drug transfer system to be used for curing traumata by modifying the coating-type liquid-phase release film for industrial uses; a release polymer produced thereby; and a product containing the same. The production process is a two-stage one comprising the step of suspension polymerization using vinyl acetate as a base substance and the step of bulk polymerization by remixing the same. The obtained polymer is a semiwatery and semioily material soluble in a water-alcohol mixture, and hence is useful as a novel drug transfer polymer wherein drugs are readily soluble.</p> |
