WATER-ABSORBING ADHESIVE COMPOSITIONS AND METHODS OF PRODUCING AND USING SAID COMPOSITIONS

摘要

FIELD: chemistry. ^ SUBSTANCE: invention relates to medicine. Described is an adhesive composition which is water-insoluble and water-absorbing, i.e. can absorb up to 15 wt % water or more. The composition consists of a hydrophilic film-forming polymer with at least one linear segment having several repeating polar groups along the polymer backbone chain, a complementary multifunctional polymer with several repeating functional groups which are not covalently bonded with the polar groups on the film-forming polymer, and a plasticiser. Described also is a method of preparing the adhesive composition. ^ EFFECT: adhesive composition adheres to a wet surface and does not dissolve or lose adhesiveness when it absorbs water. ^ 68 cl, 27 dwg, 22 tbl, 13 ex
