| titleOfInvention | Production of synthetic resin lens material |
| abstract | PURPOSE: To obtain easily a synthetic resin lens material freed from monomer bleeding and having a high refractive index and a high Abbe's number, by polymerizing a halogen-substituted phenyl (meth)acrylate in two steps. n CONSTITUTION: 5W30pts.wt. polymer containing at least 60wt% units corresponding to the formula (wherein R is H or methyl, X is Br or I, and m is the number of substituents X and is 3W5), e.g., 2,4,6-tribromophenyl methacrylate or 2,4,6- triiodophenyl acrylate is dissolved in 95W70pts.wt. monomer component containing at least 40wt% monomer of the formula and being liquid at a temperature ≤60°C. The obtained solution is cast-polymerized to obtain the purpose synthetic resin lens material having a refractive index (at 20°C) ≥1.58 and an Abbes's number ≥28. n COPYRIGHT: (C)1985,JPO&Japio |
