Provided is a polymer product, in which the weight average molecular weight measured by gel permeation chromatography is 250,000 or greater and the content of residual ring-opening-polymerizable monomer is 100 ppm by mass or greater but less than 1,000 ppm by mass, or a polymer product, in which the content of residual ring-opening-polymerizable monomer is from 1,000 ppm by mass to 20,000 ppm by mass and the yellow index (YI) value is 15 or less. |
