摘要： Coated product contains a substrate and a coating having a real part of the complex refractive index of at least 1.70, an imaginary part of the complex refractive index of not more than 0.016, a surface roughness of less than 20 nm and a scratch resistance of not more than 0.75 mu m. The real and imaginary parts of the refractive index are measured at a wavelength of 400-410 nm. The surface roughness is measured as a Ra value using atomic force spectroscopy. The scratch resistance is determined on the surface of a polycarbonate substrate using a diamond needle having a tip radius of 50 mu m at an advancing speed of 1.5 cm/s. Independent claims are also included for the following: (1) Optical data memory containing the above coated product; and (2) Casting solution used in the production of the coated product.

摘要： A process of using of a particularly substituted phenol as a chain terminator of a polymeric resin is disclosed. The chain terminator is a member selected from among ortho-substituted phenol, metha-substituted phenol, and their corresponding coupled esters. The polymeric resin is selected among polycarbonate, polyester carbonate and polyester. The thus chain terminated resin is suitable for producing molded parts and extrudates. Also disclosed are the process for producing these polymers and processes for producing the molded parts and extrudates.
