Abstract

The present invention is a resin formed article comprising a hydrogenated syndiotactic crystalline dicyclopentadiene ring-opening polymer with an initial melting temperature of 260° C. or higher, a melting point of lower than 280° C. and a syndiotacticity of higher than 90%, and a resin film, and an injection formed article. One aspect of the invention provides a resin formed article, a resin film and an injection formed article which sufficiently reflect the properties of the hydrogenated crystalline dicyclopentadiene ring-opening polymer.

Claims (4)

1. A resin formed article comprising a hydrogenated syndiotactic crystalline dicyclopentadiene ring-opening polymer with an initial melting temperature of 260° C. or higher, a melting point of lower than 280° C. and a syndiotacticity of higher than 90%.

2. The resin formed article according to claim 1 , wherein further comprises an inorganic filler.

3. A resin film comprising a hydrogenated syndiotactic crystalline dicyclopentadiene ring-opening polymer with an initial melting temperature of 260° C. or higher, a melting point of lower than 280° C. and a syndiotacticity of higher than 90%.

4. An injection formed article comprising a hydrogenated syndiotactic crystalline dicyclopentadiene ring-opening polymer with an initial melting temperature of 260° C. or higher, a melting point of lower than 280° C. and a syndiotacticity of higher than 90%.
