摘要：A copolymer composition, especially suited for fabricating optical lensescomprising a copolymer of copolymerized comonomers which include about one toabout 25 percent by weight of an acryloxyalkylsilanol; about 0.5 to about 15 percent byweight of a polyacryloxyalkylpolysiloxane; about 5 to about 60 percent by weight of ansiloxy substituted ester of acrylic or methacrylic acid; and from about 35 to about 90percent by weight of an acrylic or methacrylic ester of an alkanol having from one totwenty carbon atoms.

Contact lenses and contact lens buttons are formed of such copolymer of

copolymerized comonomers by conventional techniques, by injection molding, and bycompression molding.
