Zusammenfassung: | An hydratable porous polymer comprising a polymerized polyorganosiloxane macromonomer of formula Iwherein c is in the range of from 0 to 5, preferably in the range of from 0 to 3;M may be the same or different and is a difunctional block of molecular weight in the range of from 100 to 8000 and wherein at least one M comprises a residue from a difunctional polymer or copolymer comprising siloxane repeat units of formula IIwhere R and R may be the same or different and are selected from the group consisting of hydrogen, optionally substituted alkyl, alkenyl, alkynyl, aryl, haloalkyl, haloalkenyl, haloalkynyl, haloaryl, heterocyclyl, and haloheterocyclyl;L is a difunctional group;and Q may be the same or different and is a polymerizable group. |
