Beschreibung
Zusammenfassung:	Polyurethane polymers are described comprising polymerized units comprising a hydroxy functional aromatic group wherein the hydroxy group has been functionalized with an adhesion promoting group. In some embodiments, the polyurethane polymer comprises polymerized units have the general structure wherein L1 and L2 are independently divalent linking groups comprising an urethane group; and RA is an adhesion promoting group bonded to the oxygen atom by means of an ionic or covalent bond. In other embodiments, film articles, laminates are described and methods of making functionalized polyurethane polymers are described. La présente invention concerne des polymères de polyuréthane comprenant des unités polymérisées comprenant un groupe aromatique à fonctionnalité hydroxy, le groupe hydroxy ayant été fonctionnalisé par un groupe favorisant l'adhérence. Selon certains modes de réalisation, le polymère de polyuréthane comprend des unités polymérisées présentant la structure générale selon laquelle L1 et L2 sont indépendamment des groupes de liaison divalents comprenant un groupe uréthane ; et RA est un groupe favorisant l'adhérence lié à l'atome d'oxygène au moyen d'une liaison ionique ou covalente. Selon d'autres modes de réalisation, l'invention porte sur des articles en film, sur des stratifiés et sur des procédés de fabrication de polymères de polyuréthane fonctionnalisés.
