Zusammenfassung:	SE PROPORCIONA UN COMPUESTO DE LA FORMULA GENERAL: EN DONDE A ES 1,2,3 O 4; X ES -O-,-S- O -NR{SUP,3}-; R{SUP,3} ES H O UN RADICAL MONOVALENTE ALQUILO; Y R ES SELECCIONADO DE UN RADICAL ORGANISILICICO, UN RADICAL QUE CONTENGA UN HETEROCICLO, UN RADICAL QUE CONTENGA UN ADAMANTILO, UN RADICAL ALQUILENO, UN RADICAL FLUOROALQUILENO Y UN RADICAL HIDROXIALQUILO. Novel monomers of the general formula where b is 0 or 1, a is 1, 2, 3 or 4, R is a monovalent alkyl radical and R is an organic radical. The novel monomers may be employed to produce novel copolymers useful as hydrogel, soft non-hydrogel and/or rigid gas permeable contact lens materials.
