| abstract |
Novel organic glass with a high refractive index comprising a copolymer of (a) a diallyl isophthalate monomer, (b) an allyl or methallyl benzoate monomer and (c) a diester of maleic acid and/or diester of fumaric acid monomer, which also shows excellent light resistance and excellent other physical properties such as excellent moldability, high impact resistance, high dimension stability, excellent mechanical processing properties, excellent dyeability and excellent hard coating property, and is useful as a material for optical or optoelectronic parts such as lenses, prisms, reflecting mirror and window materials. |
