| titleOfInvention |
Polymers and hard, gas-permeable contact lenses made therefrom |
| abstract |
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. |
