Abstract: A copolycarbonate optical article comprises a polycarbonate composition including: a copolycarbonate having: 2 to 60 mol % of phthalimidine carbonate units, 2 to 90 mol % of high heat carbonate units, and optionally 2 to 60 mol % of bisphenol A carbonate units. The copolycarbonate has less than 100 ppm of each of phthalimidine, high heat bisphenol, and bisphenol A monomers, and less than 5 ppm of various ions, and is prepared from monomers each having a purity of at least 99.6%. The polycarbonate composition has a glass transition temperature of 200° C. to and a yellowness index of less than 30.

Abstract: Melt polymerization processes for producing photoactive additives are disclosed. The photoactive additives are cross-linkable polycarbonate resins formed from a benzophenone, a dihydroxy chain extender, a carbonate precursor, and a catalyst. The additives can be produced without the use of phosgene or dichloromethane, and can be cross-linked with other polymers upon exposure to UV radiation.
