摘要: The present invention relates to novel polymers, to processes for the preparation thereof, to contact lenses consisting substantially of those polymers and to processes for the manufacture thereof and to the use of the novel polymers for the manufacture of contact lenses. The polymers according to the invention are especially the copolymerisation products of monomer mixtures comprising the following monomers:______________________________________ a) 20-60% siloxane monovinyl component b) 1-25% siloxane oligovinyl component c) 10-55% fluorine-containing vinyl component d) 3-30% hydrophobic vinyl component having a bulky hydrocarbon radical, e) 0-10% hydrophilic vinyl component f) 0-15% additional cross-linking vinyl component. ______________________________________ The novel polymers and the contact lenses made therefrom are distinguished by a high degree of hardness while at the same time being highly permeable to oxygen.

摘要: The invention relates to a process for rendering contact lenses hydrophilic, which comprises treating a contact lens with a compound of formula IAr--Z--Ar' (I)wherein Ar and Ar' are each independently of the other an aromatic radical that may be substituted by lower alkoxy and/or by lower alkyl and wherein one of the radicals Ar and Ar' or both radicals Ar and Ar' contain one or more substituents X selected independently of one another from a polar functional group Y, lower alkyl substituted by a polar functional group Y, and lower alkoxy substituted by a polar functional group Y, and wherein Z is a divalent group that separates Ar and Ar' from each other by from one to six atoms. The invention relates also to contact lenses treated according to the invention and to the use of compounds of formula I in the process according to the invention.

摘要: The invention relates to contact lenses made from a polymer comprising macrocycles that are made up of units of formula I--(--CR.sup.1 .dbd.CR.sup.2 --A--)-- (I)wherein A is alkylene or alkenylene each having from 3 to 10 carbon atoms and each of which may be substituted by one or more R.sup.3 radicals, each of R.sup.1 and R.sup.2, independently of the other, is hydrogen or lower alkyl, and R.sup.3 is lower alkyl, fluorinated lower alkyl or a siloxane radical.They exhibit a combination of a high degree of hardness and oxygen permeability. They can be produced in an especially advantageous manner, that is to say by hot compression moulding.
