Abstract

A polymerization product suitable for contact lenses contains at least 30% by weight of units of an organosiloxane monomer having the following general formula <IMAGE> wherein n is an integer of 1 to 3, X is <IMAGE> in which p is an integer of 2 to 4 and q is 0 or an integer of 1 to 3, and Y<1>, Y<2> and Y<3> are methyl group or -O-Si-(CH3)3, and may also contain units of a hydrophobic methacrylic acid alkyl ester monomer, a hydrophilic monomer or a crosslinking monomer. The polymerization product has excellent oxygen permeability and proper hydrophilic property, is substantially water-nonabsorptive, and contact lenses made thereof can be comfortably worn continuously for a long period of time. The products are preferably prepared by bulk polymerization.
