Abstract
El procedimiento para preparar dicho producto de polimerizacion utiliza una mezcla de monomeros que consiste de prepolímeros de silicona que tienen laformula general (1) donde: A es un radical insaturado activado: A es un radical insaturado activado o un grupo alquilo; R1-R10 son independientemente un grupoalquilo, fluoroalquilo, alcohol, éter o fluoroéter C1-10, o un grupo aromático C6-18; m, n y p son independientemente 0 a 200, siendo m+n+p de 15 a 200; a es 1a 10, y b es 0 a 10; donde el pre polímero de silicona es preparado por reaccion de un siloxano cíclico (D) y un dimetacrilato disiloxano (M2) en presencia deun catalizador. La mejora consiste en anadir al menos un disiloxano (T2) de formula (2), donde R11-R16 son independientemente un grupo alquilo C1-5, a lamezcla de reaccion utilizada para formar el prepolímero de silicona. Se describe el hidrogel obtenido y la lente de contacto y la lente intraocular que seforman con dicho hidrogel.
