Polyester resin composition and optical material
2004
The present invention provides an optical material suitable for a resin composition, the resin composition is small birefringence and excellent transparency, mechanical strength, dimensional stability, high heat resistance, good fluidity, and retention of optical characteristics and moldability balance. The present invention provides a resin composition is obtained by containing polyester polymers and polycarbonates fluorene dihydroxy compound formed by mixing; said polymer is a polyester formed from dicarboxylic acid compound and a dihydroxy compound of the dicarboxylic acid compound comprises an alicyclic dicarboxylic acid and / or alicyclic dicarboxylic acid ester-forming derivative thereof. The resin composition of the present invention can be applied to the optical material a camera lens, an eyeglass lens, an optical disk, an optical fiber, the optical sheet or the like.
