摘要

according to the invention, the general of the city. it is the use of the compounds in the preparation of high quality polyurethane optical material and manufacturing method for the resin composition material and made in the optical material. according to the invention, the lens, so as to get the most from the adhesive tape can be white emission occurs and in order to solve the political process, obtained from this compound to adjust ph 3.1 to 7, to increase the reaction speed, on the edge of lens. no white, no obvious aggregation is not balanced to provide polyurethane in optical materials.
