Thermoplastics with High Refractive Index and High Abbes Number
Thermosets and thermoplastics with high refractive indices (nD) and high Abbes numbers (vD) are attracting significant interest because of their application as optical materials such as lenses, prisms, and waveguides that is made possible by their light weight, impact resistance, processability, and dying ability as compared to inorganic glasses. The former such as resins from episulfides, polythiols, and polyisocyanates, have been developed for consumer use such as eyeglasses that are manufactured by cast molding. On the other hand, the latter such as poly(methyl methacrylate), polycarbonate, and cycloolefin polymers are used in camera, pick-up, and projector lenses where injection molding is applied.Thermosets exhibiting both high nD and high vD have been reported in patents as described above and in papers However, thermoplastics with high nD and high vD have so far not been the subject of detailed investigation. Therefore, the development of high nD thermoplastics with high vD values is a challengingtopic.
