Title
(EN) USE OF PENDANT FREE-RADICALLY POLYMERIZABLE MOIETIES WITH POLAR POLYMERS TO PREPARE HYDROPHILIC PRESSURE SENSITIVE ADHESIVE COMPOSITIONS
(FR) UTILISATION DE FRAGMENTS PENDANTS A POLYMERISATION RADICALAIRE AINSI QUE DE POLYMERES POLAIRES EN VUE DE LA PREPARATION DE COMPOSITIONS ADHESIVES HYDROPHILES ET SENSIBLES A LA PRESSION
Abstract
(EN)
Cross-linked, hydrophilic pressure sensitive adhesive compositions, (meth)acrylate-functional polar polymers which serve as precursors to them, and medical products using such adhesives are disclosed. The cross-linked polymer is prepared by free-radically cross-linking reactive polymers that are functionalized with pendant polymerizable moieties. Medical products that include such compositions are biomedical electrodes, pharmaceutical delivery devices, and medical skin coverings such as wound dressings.
(FR)
La présente invention concerne des compositions adhésives, hydrophiles, sensibles à la pression et réticulées, des polymères polaires à fonctionnalité (méth)acrylate servant de précurseurs de ces compositions, ainsi que des produits à usage médical faisant appel à de tels adhésifs. Le polymère réticulé est obtenu par la réticulation radicalaire de polymères réactifs qui sont fonctionnalisés à l'aide de fragments polymérisables pendants. Les produits à usage médical comprenant ces compositions consistent en des électrodes biomédicales, des dispositifs d'apport pharmaceutique, ainsi qu'en des couvertures cutanées médicales tel que des pansements.
