Abstract
La invención se refiere a un proceso novedoso para producir moldeos, especialmente lentes de contacto, el cual comprende los siguientes pasos: a) preparar una solución sustancialmente acuosa de un prepolímero soluble en agua que contenga grupos reticulables. b) convertir la solución resultante al estado sólido. c) introducir la solución en estado sólido resultante en un molde. d) convertir la solución en estado sólido, al estado líquido en el molde. e) en donde sea aplicable, cerrar el molde. f) iniciar la resticulación g) en donde sea aplicable, abrir el molde, de tal manera que pueda se pueda remover el moldeo del molde.The invention relates to a novel process for producing molds, especially contact lenses, which comprises the following steps: a) preparing a substantially aqueous solution of a water soluble prepolymer containing crosslinkable groups. b) converting the resulting solution to the solid state. c) introducing the resulting solid state solution into a mold. d) converting the solution in the solid state to the liquid state in the mold. e) where applicable, close the mold. f) start the reticulation g) where applicable, open the mold, so that the mold can be removed from the mold.
