Abstract

Se describen composiciones y métodos para mejora el desprendimiento de moldes de resina polar utilizados en la producción de materiales de hidrogel de silicona. Las presentes composiciones y métodos incluyen el uso de uno o más agentes de desprendimiento de moldes reactivos. Los agentes de desprendimiento de molde reactivos, reaccionan con componentes de una mezcla de polimerización para producir un dispositivo de hidrogel de silicona polimerizado que contiene un producto reactivo del agente de desprendimiento de molde y los otros componentes de la mezcla de polimerización. Los moldes de resina polar empleados durante la polimerización de la mezcla de polimerización, se separan más fácilmente que moldes sustancialmente idénticos empleados en la polimerización de un material sustancialmente idéntico sin un agente de desprendimiento de molde reactivo. Las presentes composiciones y métodos pueden emplearse en la fabricación de lentes de hidrogel de silicona, tales como lentes de contacto. Los auxiliares de desprendimiento de molde también pueden ser útiles como auxiliares para desmoldar lentes oftálmicos.
