Process for making a polymer for an optical substrate by hydrogenating a cycloolefin copolymer |
| 摘要 |
Substantially optically clear molding compositions comprising polymerized cycloolefin monomers (e.g., norbornene-type polymers) which, subsequent to polymerization have been hydrogenated are provided. The polymers have a weight average molecular weight of from about 37-47x103.
