- Application Filed: April 03, 2003
- Claim: 1. A method of moulding materials in which a mould is used having a plurality of mould components with moulding surfaces together defining a moulding cavity, said method comprising the step of forming at least part of the mould components of a polymerisable material and polymerising said material under polymerisation conditions, characterized in that, the starting material before polymerisation is a polymerisable compound of the formula: [chemical expression included] wherein Z and Y independently represent polymerisable groups.
- Claim: 2. A method according to claim 1, characterized in that said polymerisable groups Z and Y are independently chosen from the groups consisting of (meth)acrylate, oxetane, glycidylether, allylether, epoxy, vinylether and vinylester, or mixtures thereof, wherein Z or Y can be also a thiol group in combination with other radically polymerisable monomers in such a way that crosslinked polymers are obtained.
- Claim: 3. A method according to claim 1, characterized in that the starting material is 2,2′-(2,2,3,3,4,4,5,5-octafluoro 1,6-hexanyloxymethyl)diepoxide, wherein both Y and Z are glycidylether groups.
- Claim: 4. A method according to claim 1, characterized in that the starting material is 2,2,3,3,4,4,5,5-octafluoro 1,6-hexanediol-dimethacrylate wherein both Y and Z are methacrylate groups.
- Claim: 5. A method according to claim 1, characterized in that the F/C-ratio (Fluoro-Carbon ratio) of said polymerisable compound should be higher or equal to 8/14.
- Claim: 6. A method according to claim 1, characterized in that the moulding cavity being shaped for moulding an optical component therein.
- Claim: 7. A method of moulding materials in which a mould is used having a plurality of mould components with moulding surfaces together defining a moulding cavity, said method comprising the step of forming at least part of the mould components of a polymerisable material, polymerising said material for forming the mould, filling the moulding cavity with a mixture of moulding material, applying UV-light or heat to said moulding material in the mould to set or cure the moulding material, continuing the UV-light or heat treatment until sufficient stiffness has developed in the moulded article and removing the moulded article thus made from the mould, wherein said mould is made of polymerising a polymerisable compound of the formula [chemical expression included] wherein Z and Y independently represent polymerisable groups.
- Claim: 8. A method according to claim 7, characterized in that said polymerisable groups Z and Y are independently chosen from the groups consisting of (meth)acrylate, oxetane, glycidylether, allylether, epoxy, vinylether and vinylester, or mixtures thereof, wherein Z or Y can be also a thiol group in combination with other radically polymerisable monomers in such a way that crosslinked polymers are obtained.
- Claim: 9. A method according to claim 7, characterized in that the starting material is 2,2,3,3,4,4,5,5-octafluoro 1,6-hexanediol-dimethacrylate wherein both Y and Z are methacrylate groups.
- Claim: 10. A method according to claim 7, characterized in that the starting material is 2,2′-(2,2,3,3,4,4,5,5-octafluoro 1,6-hexanyloxymethyl)diepoxide wherein both Y and Z are glycidylether groups.
- Claim: 11. A method according to claim 7, characterized in that the F/C-ratio (Fluoro-Carbon ratio) of said polymerisable compound should be higher or equal to 8/14.
- Claim: 12. Optical components obtained according to a method as disclosed in claim 7.
- Claim: 13. A mould for making optical components comprising a plurality of mould components with moulding surfaces together defining a moulding cavity, wherein said mould is obtained by polymerising a mixture comprising, as a main constituent thereof, a polymerisable compound of the formula: [chemical expression included] wherein Z and Y independently represent polymerisable groups.
- Claim: 14. A mould according to claim 13, characterized in that said polymerisable groups Z and Y are chosen from the group consisting of (meth)acrylate, oxetane, glycidylether, allylether, epoxy, vinylether and vinylester, or mixtures thereof, wherein Z or Y can be also a thiol group in combination with other radically polymerisable monomers in such a way that crosslinked polymers are obtained.
- Claim: 15. A mould according to claim 13, characterized in that the starting material is 2,2,3,3,4,4,5,5-octafluoro 1,6-hexanediol-dimethacrylate wherein both Y and Z are methacrylate groups.
- Claim: 16. A mould according to claim 13, characterized in that the starting material is 2,2′-(2,2,3,3,4,4,5,5-octafluoro 1,6-hexanyloxymethyl)diepoxide wherein both Y and Z are glycidylether groups.
- Claim: 17. A mould according to claim 13, characterized in that the F/C-ratio (Fluoro-Carbon ratio) of said polymerisable compound should be higher or equal to 8/14.
- Claim: 18. A mould according to claim 13, characterized in that the shape of the mould being spherical or a-spherical made of said polymerisable material wherein the aspect ratio of the layer thickness made of said material can be as large as 50.
