Polyester, moldings thereof, and process for production of the polyester |
| abstract |
The aim of the invention is to stably provide a polyester polymer which has excellent transparency, mechanical and electric characteristics, and extremely low optical anisotropy and excellent moldability and size stability for engineering plastics, particularly suitable for optical materials. The above-mentioned problem can be achieved by a polyester polymer, obtainable from a dicarboxylic acid compound and a dihydroxy compound, wherein the dicarboxylic acid compound comprises an alicyclic dicarboxylic acid and/or its ester-forming derivative, n nthe dihydroxy compound comprises a compound of the general formula (1): n n; and a content of a diethylene glycol in the polyester polymer is 6 mol % or lower. |
