Abstract
An optical polymer satisfying an expression: (ηA−ηB)/ηB×100<60, where, ηA is the melt viscosity of the optical polymer measured at a temperature of 290° C. and a shear rate of 200 (l/s), and ηB is the melt viscosity of the optical polymer measured at a temperature of 290° C. and a shear rate of 2000 (l/s).
