Abstract

La présente invention concerne une composition thermosensible prévenant l'adhérence au tissu et un procédé de préparation de cette composition. Plus spécifiquement, la présente invention concerne une composition thermosensible prévenant l'adhérence au tissu qui contient aussi un médicament qui inhibe sélectivement une réponse inflammatoire, et un procédé de préparation de cette composition. La composition est fabriquée par réaction chimique par l'addition d'un agent de réticulation à une solution aqueuse. Cette solution aqueuse contient : un copolymère bloc contenant un bloc polyéthylèneoxyde possédant la capacité de supprimer l'adhérence au tissu, et un polymère d'un poids moléculaire compris entre 10,000 et 1,000,000 g/mol qui peut être mélangé avec ce copolymère. Cette composition se caractérise aussi en ce que les différences de viscosité, d'absorbance de région visible, et de stabilité entre les couches supérieure et inférieure liquides sont inférieures ou égale à 10% lors de la centrifugation de la composition. De plus, le procédé de préparation de cette composition améliore l'homogénéisation de réticulation et la stabilité de viscosité par des procédés de pulvérisation et de malaxage simultanés sans retardant de réaction. Selon la présente invention, des débris flottants sur une fibre causés par une réticulation non uniforme peuvent non seulement être empêchés, mais l'homogénéisation de réticulation et la stabilisation de viscosité peuvent aussi être améliorées. Par conséquent, cette composition peut être uniformément appliquée sur une blessure d'une personne et elle possède une haute stabilité et d'excellents effets pour empêcher l'adhérence au tissu.
