Priority Data:
(EN) The disclosed technology provides thermoplastic polyurethane compositions having non-leaching antimicrobial properties while still maintaining good physical properties, methods of making the same, and articles, including medical devices, made from such compositions. The disclosed technology includes a process of making an antimicrobial polymer composition, where the process includes mixing an antimicrobial additive into a polymeric material; wherein said polymeric material comprises a polymeric backbone made up of urethane linkages derived from a polyisocyanate and a polyol; and wherein said mixing occurs under conditions that result in the breaking of a minority of said urethane bonds resulting in reactive isocyanate groups; and wherein two or more of said reactive isocyanate groups react with said antimicrobial additive to covalently bond said antimicrobial additive into the polymeric backbone of said polymeric material; resulting in an antimicrobial polymer composition.
(FR) L'invention concerne des compositions de polyuréthanne thermoplastique ayant des propriétés antimicrobiennes non lixiviantes, tout en conservant encore de bonnes propriétés physiques, des procédés de fabrication de ces compositions, et des articles, y compris des dispositifs médicaux, fabriqués à partir de ces compositions. La technologie exposée comprend un procédé de fabrication d'une composition polymère antimicrobienne, le procédé comprenant le mélange d'un additif antimicrobien à un matériau polymère ; ledit matériau polymère comprenant un squelette polymère constitué de liaisons uréthanne dérivant d'un polyisocyanate et d'un polyol ; et ledit mélange ayant lieu dans des conditions qui conduisent à la rupture d'une minorité desdites liaisons uréthanne, pour donner des groupes isocyanate réactifs ; et deux desdits groupes isocyanate réactifs ou plus réagissant avec ledit additif antimicrobien pour lier par liaison covalente ledit additif antimicrobien au squelette polymère dudit matériau polymère ; avec obtention d'une composition polymère antimicrobienne.
