A kind of optical polycarbonate resin and preparation method thereof |
| abstract |
The invention provides an optical polycarbonate resin and a preparation method thereof. The resin introduces nitrogen element and benzene ring structure to improve the refractive index of polycarbonate, and at the same time introduces spiro ring structure to improve the formability of polycarbonate, the combination of the three can make polycarbonate have both high refractive index and easy formability. The present invention also provides a preparation method of the resin. The resins can be used to manufacture optical articles such as optical lenses and optical lens compositions. |
