Abstract
The present invention is: a hydrogenated tetracyclododecene-based ring-opening polymer comprising a repeating unit (A) derived from tetracyclododecene in a ratio of 40 wt % or more based on a total amount of repeating units, a ratio of meso diads in the repeating unit (A) being 65% or more; and a method for producing the same. By means of the present invention, provided are: a crystalline hydrogenated tetracyclododecene-based ring-opening polymer having a high melting point and a high glass transition temperature, and exhibiting excellent heat resistance and excellent processability even after forming due to melt forming; and a method for producing the same.
