Abstract

La presente se refiere a un proceso para la fabricacion de un artículo moldeado, el cual comprende los pasos de: a) preparar una solucion acuosa que comprende un prepolímero soluble en agua que tiene grupos reticulables, y un polímero adicional que no tiene grupos reticulables; b) introducir la solucion obtenida en un molde; c) desencadenar la reticulacion y d) abrir el molde, de tal manera que se pueda remover el artículo moldeado del molde. De acuerdo con el proceso de la presente, se pueden fabricar artículos moldeados, tales como lentes de contacto, con una mejor calidad y un mejor rendimiento global.
