Abstract

Se describe un macromonómero de la fórmula I: Q-(PFPE-L)n-1 - PFPE-Q (I) en donde n es mayor 1,0; PFPE puede ser igual o diferente y es un poliéter perfluorado de fórmula II: -OCH2 CF2O (CF2CF2O) X (CF2O) y CF2CH2O - (II) en donde las unidades CF2 CF2O y CF2O pueden ser didtribuidas al azar o distribuidas como bloques a través de la cadena en donde x e y pueden ser iguales o diferentes de tal modo que el peso molecular del PFPE está en el rango de desde 242 a 4000, L es un grupo ligante difuncional; y Q puede ser igual o diferente y es un grupo polimerizable. El macrómero puede ser usado preferentemente en la producción de lentes de contacto.A macromonomer of the formula I is described: Q- (PFPE-L) n-1 - PFPE-Q (I) where n is greater than 1.0; PFPE can be the same or different and is a perfluorinated polyether of formula II: -OCH2 CF2O (CF2CF2O) X (CF2O) and CF2CH2O - (II) where CF2 CF2O and CF2O units can be randomly distributed or distributed as blocks through of the chain where x and y can be the same or different such that the molecular weight of the PFPE is in the range of from 242 to 4000, L is a difunctional binding group; and Q can be the same or different and is a polymerizable group. The macromer can be used preferably in the production of contact lenses.
