Abstract

UNA COMPOSICION POLIMERICA UTIL PARA SU USO EN APARATOS OFTALMICOS TALES COMO LENTES DE CONTACTOS, LENTES INTRAOCULARES Y OTROS APARATOS MEDICOS Y NO-MEDICOS, QUE COMPRENDE UN COPOLIMERO QUE INCORPORA UNIDADES DE REPETICION QUE CONTIENEN UN GRUPO SOLVOLIZABLE Y VARIAS UNIDADES DE REPETICION HIDROFILICA EN PROPORCIONES DETERMINADAS, QUE ES MECANICAMENTE ESTABLE Y DESPUES DE LA HIDRATACION, LAS DIMENSIONES DE LOS ARTICULOS POLIMERICOS FORMADOS DE LO ANTERIOR PUEDA SER CONTROLADA. EN PARTICULAR, LAS COMPOSICIONES HIDROFILICAS RESULTANTE DE LA INVENCION SON UTILES EN APLICACIONES DONDE LAS FUERZAS Y DISTORSIONES DEL ARTICULO POLIMERO DEBIDO A LA ABSORCION DE AGUA, ETC., QUE DEBEN SER MINIMIZADO O, SI ES POSIBLE, ELIMINADA.
