Polycarbonate copolymer and method of producing the same |
| abstract |
The problem to be solved by the present invention is to provide a polycarbonate copolymer containing a plant-derived raw material, which is excellent in the mechanical strength and heat-resistant and assured of small refractive index, large Abbe number, small birefringence and excellent transparency. The present invention provides a polycarbonate copolymer containing a constitutional unit derived from a dibydroxy compound represented by the following formula (1) and a constitutional unit derived from an alicyclic dihydroxy compound, wherein the ratio of the dihydroxy compound represented by the following formula (1) and the alicyclic dihydroxy compound to all dihydroxy compounds constituting said copolymer is 90 mol% or more. |
