Abstract
A hydrogenated norbornene-based ring-opening polymer having a syndiotacticity ((racemo diads)/(meso diads+racemo diads)×100) of more than 90% is disclosed. A method for producing the same is also disclosed. It is thus possible to provide a hydrogenated highly syndiotactic norbornene-based ring-opening polymer that is formed of a single material, and exhibits high solvent resistance, and a method for producing the same.
