    摘要: Hard polymers with extremely high oxygen permeability are described, which consist of the copolymerization product of 1-15% by weight of a poly(dimethylsiloxane) bearing multiple polymerizable vinyl groups and having a number-average molecular weight M.sub.n of 1000-7000, 20-50% of an oligosiloxanylalkyl (meth)acrylate, 25-50% of an at least three fluorine atoms containing vinyl-monomer, 0-30% of copolymerizable monomers, which by themselves as homo- or copolymers have a Shore-D hardness of at least 85, 1-25% of polyvinyl-crosslinking monomer of 200-1000 molecular weight, and 0-15% of a watersoluble, copolymerizable monomer. The novel polymers combine a Shore-D hardness of 70-85 with an oxygen permeability of 40-90 barrers, making them outstanding materials for the manufacture and use as rigid, gas-permeable contact lenses.

    摘要: The instant invention pertains to a method and a fluid composition for producing contact lenses with improved lens quality and with increased product yield. The method of the invention involves adding a phospholipid into a fluid composition including a lens-forming material in an amount sufficient to reduce an averaged mold separation force by at least about 40% in comparison with that without the phospholipids.
