ABSTRACT:
The present invention relates to novel hydrocolloid adhesive masses consisting of an adhesive mixture based on a low molecular polyisobutylene and a poly(styrene/olefin/styrene) block polymer, and of a cellulose derivative, with which an acrylate polymer with a glass transition temperature below −20° C. is associated for the purpose of increasing the resistance to deterioration of the absorption capacity of said hydrocolloid adhesive mass after radiosterilization.The invention further relates to the use of these novel hydrocolloid adhesive masses for medical, dermatological or cosmetic purposes and particularly for the production of dressings for the treatment of blisters, exudative wounds, burns and superficial, deep, chronic or acute dermo-epidermal lesions.
