OPTICAL THERMOPLASTIC RESIN AND FORMED BODY |
| 摘要 |
An optical thermoplastic resin has a rate of reduction in melt viscosity of less than 20%, an orientation birefringence of −1.7×10−4 to 1.7×10−4, a photoelastic constant of −3.7×10−12 to 3.7×10−12 Pa−1, and, when formed into a 2 mm-thick formed body, has a haze of 1% or less. |
