Abstract

Un polímero poroso hidratable que comprende un macromonómero de poliorganosiloxano polimerizado de la fórmula I: Q-[M-L]c -M-Q (I) en donde C está en la escala de 0 a 5, de preferencia en la escala de 0 a 3; M puede ser igual o diferente, y es un bloque difuncional de un peso molecular en la escala de 100 a 8000 y en donde cuando menos un M comprende un residuo de un polímero o copolímero difuncional que comprende unidades de repetición de siloxano de la fórmula II R1; OSi; R2; en donde R1 y R2 pueden ser iguales o diferentes, y se seleccionan a partir del grupo que consiste en hidrógeno, alquilo opcionalmente sustituido, alquenilo, alquinilo, arilo, haloalquilo, haloalquenilo, ahloalquinilo, haroarilo, heterocíclico y haloheterocíclico; L puede ser igual y diferente, y es un grupo de enlace difuncional, y Q puede ser igual o diferente, y es un grupo polimerizable.A hydratable porous polymer comprising a polymerized polyorganosiloxane macromonomer of the formula I: Q- [M-L] c -M-Q (I) wherein C is on the scale of 0 to 5, preferably on the scale of 0 to 3; M may be the same or different, and is a difunctional block with a molecular weight on the scale of 100 to 8000 and where at least one M comprises a residue of a difunctional polymer or copolymer comprising siloxane repeating units of formula II R1; Or if; R2; wherein R1 and R2 may be the same or different, and are selected from the group consisting of hydrogen, optionally substituted alkyl, alkenyl, alkynyl, aryl, haloalkyl, haloalkenyl, ahloalkynyl, haroaryl, heterocyclic, and haloheterocyclic; L can be the same and different, and is a difunctional linking group, and Q can be the same or different, and is a polymerizable group.
