An object of the present invention is to provide a thermoplastic resin for optics and a molded body comprising the same, which are excellent in both the birefringence and the photoelastic birefringence of the optical thermoplastic resin, and have excellent transparency and color tone. The stability is also excellent.nThe present invention relates to a thermoplastic resin for optical use, which has a melt viscosity reduction rate of less than 20%, an orientation birefringence of -1.7×10-4 to 1.7×10-4, and a photoelastic constant of -3.7×10-12 to 3.7×. When the molded body having a thickness of 2 mm is formed at 10-12 Pa-1, the haze is 1% or less. |
