    摘要: The present disclosure is concerned with self-adhesive sheet-like structures made by adhering an adhesive polyurethane gel material to a supporting substrate and the utilization of such structures in the medical field to adhere materials such as plasters, wound dressings and appliances to the human body, and in other fields to connect articles, such as the parts of a fractured or cracked object, to one another by means of an adhesive bond. The gel is formed by immobilizing a high molecular weight polymeric polyol in the matrix of a covalently crosslinked polyurethane which is prepared by reacting polyisocyanates having an isocyanate functionality of at least 2 with higher molecular weight polyhydroxyl compounds having a hydroxyl functionality of at least 3. These reactants are selected in accordance with the following formula which relates the isocyanate number, K, (isocyanate to hydroxyl equivalents ratio times 100) to the average functionalities of the polyisocyanates (F.sub.I) and of the polyhydroxyl compounds (F.sub.P) as follows: ##EQU1## wherein X is less than or equal to 120. These reactants are also selected to give a weight ratio of matrix to immobilized polymeric polyol of between about 15:85 and 62:38.
