METHOD OF PREPARING LOW HAZE POLYMER COMPOSITIONS FOR USE IN HIGH REFRACTIVE INDEX OPTICAL MATERIALS
Publication number: 20230147118Abstract: A method of preparing a low bubbling and low yellowing, high refractive index polyurethane or polythiourethane is provided. A method of evaluating an aromatic polyiso(thio)cyanate material, such as an aromatic diisocyanate, e.g., m-xylylene cyanate, is provided. The method evaluates transmittance in a sample of the isocyanate to determine if the aromatic polyiso(thio)cyanate material will lead to unacceptable bubbling or yellowing in a high refractive index or high Abbe number polymer composition.Type: ApplicationFiled: March 24, 2021Publication date: May 11, 2023Applicant: PPG Industries Ohio, Inc.Inventors: Barry R. Havens, Darrin R. Dabideen, Matthew S. Luchansky, Nigel D. Kidder-Wolff -
