Abstract

PROCESSO DE FABRICAçãO DE UM GEL RETICULADO BIOCOMPATìVEL,GEL,E,UTILIZAçãO DO GEL A invenção refere-se a um processo de fabricação de um gel reticulado biocompatível que envolve as etapas: de iniciação da reticulação de uma quantidade determinada de pelo menos um polímero biocompatível em solução por adição de uma quantidade de agente reticulante, de reação de reticulação da dita quantidade de polímero, de adição de uma quantidade suplementar de polímero de massa molecular superior a 500 000 Da em solução com diluição da mistura da reação de maneira a diminuir a concentração global do polímero em solução e de reticulação e de interrupção da reação de reticulação por eliminação do agente reticulante; assim como o dito gel e utilização do mesmo.
