HIGH REFRACTIVE INDEX THERMOPLASTIC POLYPHOSPHONATES

摘要

High refractive index, melt processable polyphosphonates and methods for preparing the same are provided. These poylmers are particularly useful for optical and ophthalmic parts, such as lenses. A method of preparing optical and ophthalmic lenses by injection molding the polymers of the present invention into the form of the optical or ophthalmic lenses is also provided
