摘要
The present invention provides a hydrogenated syndiotactic crystalline dicyclopentadiene ring-opening polymer having a melting point of lower than 280° C., an initial melting temperature of 260° C. or higher and a syndiotacticity of higher than 90%, and a syndiotactic dicyclopentadiene ring-opening polymer, and a method for producing the syndiotactic dicyclopentadiene ring-opening polymer, and a method for producing the hydrogenated syndiotactic crystalline dicyclopentadiene ring-opening polymer. The hydrogenated syndiotactic crystalline dicyclopentadiene ring-opening polymer has a sufficiently high initial melting temperature, excellent heat resistance and advantageous industrial producibility. The syndiotactic dicyclopentadiene ring-opening polymer is excellent in solution stability after polymerization reaction and can be converted into the hydrogenated product by hydrogenation reaction.
