Abstract[English]
The invention relates to the technical field of pressure-sensitive adhesives, in particular pressure-sensitive adhesives for bonding to the skin as they are used in plasters, further medical dressings and increasingly in sensors to be attached to the skin and similar products. Specifically, the invention proposes a pressure-sensitive adhesive comprising a polyhydroxy alkanoate, characterized in that the polyhydroxy alkanoate features 1 to 20 weight- % of structural units having a side chain functionalization moiety comprising at least 10 C-atoms.[French]
L'invention concerne le domaine technique des adhésifs sensibles à la pression, en particulier des adhésifs sensibles à la pression pour la liaison à la peau lorsqu'ils sont utilisés dans des plâtres, d'autres pansements médicaux et de plus en plus dans des capteurs à fixer sur la peau et des produits similaires. En particulier, l'invention concerne un adhésif sensible à la pression comprenant un polyhydroxyalcanoate, caractérisé en ce que le polyhydroxyalcanoate présente 1 à 20 % en poids d'unités structurales ayant une fraction de fonctionnalisation de chaîne latérale comprenant au moins 10 atomes de C.
