PREPARATION OF HYDROPHILIC PRESSURE-SENSITIVE ADHESIVES WITH OPTIMIZED ADHESIVE PROPERTIES Russian patent published in 2006 - IPC C09J201/00 C09J139/06 

FIELD: adhesives.

SUBSTANCE: preparation of hydrophilic pressure-sensitive adhesives allows obtaining adhesives with a particular optimized degree of adhesion. Composition thus obtained contains hydrophilic polymer and complementary short-chain plasticizer, said polymer and said plasticizer being capable of forming hydrogen and electrostatic bonds with each other and are present in proportion optimizing essential characteristics of adhesive composition such as adhesion strength, cohesion strength, and hydrophilicity. Composition may be, for instance, employed as medicinal adhesive for being applied onto skin or other body surface, in drug transportation systems such as, for instance, topical, transdermal, transmucosal systems, by therapeutical iontophoresis, in medicinal cutaneous plaster, wound-healing products, and in biomedical electrodes.

EFFECT: optimized adhesive properties.
