titleOfInvention | Organic glass for optical parts |
abstract | ABSTRACT OF THE DISCLOSURE The invention provides an organic glass for optical parts, in which the main polymer component is constituted by a bipolymer consisting of (a) a diallyl ester of diphenic acid, and (b) an urethane acrylate having vinyl groups introduced into both its ends by the reaction of a chainlike polyurethane having hydroxyl groups at both its ends, obtained by the reaction of a diisocyanate component with a diol component, with acrylic or methacrylic acid. This organic glass for optical parts has a high refractive index and excels in transmittance, impact resistance and other physical properties as well, so that it can be applied to optical parts to which only inorganic glass has been applied so far in the art. |
