Abstract

"PROCESSO PARA A FABRICAçãO DE MOLDAGENS". A invenção refere-se a um processo para a fabricação de uma moldagem, compreendendo as etapas de a) preparar uma solução aquosa compreendendo um pré-polímero solúvel em água tendo grupos reticuláveis e um polímero adicional, o qual está isento de grupos reticuláveis, b) introduzir a solução obtida em um molde, c) iniciar a reticulação, e d) abrir o molde de modo tal que a moldagem possa ser removida do molde. De acordo com o processo da invenção, as moldagens, tais como as lentes de contato, podem ser fabricadas com uma qualidade aperfeiçoada e um rendimento global aperfeiçoado.
