발명의 명칭: (EN) POLYMER COMPOSITIONS CONTAINING GRAFTED POLYMERIC NETWORKS AND PROCESSES FOR THEIR PREPARATION AND USE
(FR) COMPOSITIONS POLYMÈRES CONTENANT DES RÉSEAUX POLYMÈRES GREFFÉS ET LEURS PROCÉDÉS DE PRÉPARATION ET D'UTILISATION
요약서:
(EN) Provided are polymer compositions made by a process comprising: (a) providing a first reactive composition containing: (i) a polymerization initiator that is capable, upon a first activation, of forming two or more free radical groups, at least one of which is further activatable by subsequent activation; (ii) one or more ethylenically unsaturated compounds; and (iii) a crosslinker; (b) subjecting the first reactive composition to a first activation step such that the first reactive composition polymerizes therein to form a crosslinked substrate network containing a covalently bound activatable free radical initiator, (c) combining the crosslinked substrate network with a second reactive composition containing one or more ethylenically unsaturated compounds; and (d) activating the covalently bound activatable free radical initiator of the crosslinked substrate network such that the second reactive composition polymerizes therein with the crosslinked substrate network to form a grafted polymeric network and a byproduct polymer. Also provided are precursors to the polymer compositions, processes for preparation of the polymer compositions, and methods of using the polymer compositions, for instance in medical devices.
(FR) L'invention concerne des compositions polymères fabriquées selon un procédé consistant en : (a) la fourniture d'une première composition réactive contenant : (i) un initiateur de polymérisation qui est apte, lors d'une première activation, à former au moins deux groupes de radicaux libres, dont au moins un peut être activé davantage par une activation ultérieure ; (ii) un ou plusieurs composés à insaturation éthylénique ; et (iii) un agent de réticulation ; (b) la soumission de la première composition réactive à une première étape d'activation de telle sorte que la première composition réactive se polymérise pour former un réseau de substrat réticulé contenant un initiateur de radicaux libres activable lié par covalence, (c) la combinaison du réseau de substrat réticulé avec une seconde composition réactive contenant un ou plusieurs composés à insaturation éthylénique ; et (d) l'activation de l'initiateur de radicaux libres activable lié par covalence du réseau de substrat réticulé de telle sorte que la seconde composition réactive se polymérise avec le réseau de substrat réticulé pour former un réseau polymère greffé et un polymère sous-produit. L'invention concerne également des précurseurs des compositions polymères, des procédés de préparation des compositions polymères, et des procédés d'utilisation des compositions polymères, par exemple dans des dispositifs médicaux.
