Production manner of the constituent and the said constituent for the high refraction optical material, hardening the said constituent, the organicity glass and its production manner null for the high refraction optical material

摘要

PURPOSE: To obtain the subject glass excellent in impact resistance and transparency and useful as lenses, etc., of eyeglasses by copolymerizing raw materials containing diallyl terephthalate, etc., and a specific bromine-containing allyl ester oligomer and prepared so as to provide a prescribed viscosity and a prescribed refractive index. ;CONSTITUTION: This glass is obtained by copolymerizing a raw material which is a bromine-containing allyl ester oligomer, having a structure expressed by the formula [A is 1-20C bivalent organic residue; B is bivalent organic residue derived from a diol having one or more bromines; (n) is 1-20], containing diallyl terephthalate monomer and/or diallyl isophthalate monomer and/or diallyl phthalate monomer and prepared so as to provide 50-2000 cP viscosity at 30°C and 1.53-1.58 refractive index.;COPYRIGHT: (C)1995,JPO
