Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
