Abstract

UN POLIMERO RETICULADO DE HIDROGEL PARA LENTES DE CONTACTO CON UNA ABSORCION DE AGUA ENTRE EL 60 Y EL 70% EN PESO BASADO EN EL PESO TOTAL DE HIDROGEL SE FORMA A PARTIR DE UNA MEZCLA DE COMPONENTES MONOMEROS CONTENIENDO (1) N-VINIL-2-PIRROLIDONA, (2) ALQUIL METACRILATO Y (3) UN COMPUESTO DE FORMULA (I) EN LA QUE R1 ES UN HIDROGENO O UN GRUPO ALQUILO INFERIOR, PREFERIBLEMENTE METILO Y R2 O UN GRUPO ARILO SUSTITUIDO O NO, O UN GRUPO ALQUILO QUE CONTIENE DE 1 A 6 ATOMOS DE CARBONO SUSTITUIDOS POR UN GRUPO ARILO SUSTITUIDO O NO, O UN GRUPO ARILOXI SUSTITUIDO O NO POR UN GRUPO CICLOALQUILOXI. PREFERENTEMENTE EL METACRILATO ALQUILICO ES HIDROXIETILMETACRILATO Y EL TERCER COMPONENTE FENETILMETACRILATO. LOS AGENTES DE RETICULACION USADOS PREFERENTEMENTE TIENEN SUS DOS GRUPOS FUNCIONALES QUE DIFIEREN EN REACTIVIDAD, POR EJEMPLO ALIL METACRILATO.
