Abstract
Official abstract text for this publication.
Provided is a resin composition containing a hydrogenated crystalline dicyclopentadiene ring-opening polymer and a nucleator, wherein a content of the nucleator is 0.01 to 0.50 part by weight based on 100 parts by weight of the hydrogenated crystalline dicyclopentadiene ring-opening polymer, and a resin formed article comprising a hydrogenated crystalline dicyclopentadiene ring-opening polymer and a nucleator, wherein a content of the nucleator is 0.01 to 0.50 part by weight based on 100 parts by weight of the hydrogenated crystalline dicyclopentadiene ring-opening polymer. The resin composition containing a hydrogenated crystalline dicyclopentadiene ring-opening polymer is suitably used as a raw material for a low-polluting resin formed article, and a low-polluting resin formed article containing the hydrogenated crystalline dicyclopentadiene ring-opening polymer.
First claim
Opening claim text (preview).
The invention claimed is: 1. A resin composition comprising a hydrogenated crystalline dicyclopentadiene ring-opening polymer and a nucleator, wherein the hydrogenated crystalline dicyclopentadiene ring-opening polymer has a melting point of 200° C. or higher, the nucleator is an organic metal phosphate salt, and a content of the nucleator is 0.01 to 0.50 part by weight based on 100 parts by weight of the hydrogenated crystalline dicyclopentadiene ring-opening polymer. 2. A resin formed article comprising a hydrogenated crystalline dicyclopentadiene ring-opening polymer and a nucleator, wherein the hydrogenated crystalline dicyclopentadiene ring-opening polymer has a melting point of 200° C. or higher, the nucleator is an organic metal phosphate salt, and a content of the nucleator is 0.01 to 0.50 part by weight based on 100 parts by weight of the hydrogenated crystalline dicyclopentadiene ring-opening polymer. 3. The resin formed article according to claim 2 , wherein an amount of organic substances released when the resin formed article is heated at 100° C. for 30 minutes is 0.1 ppm or less.
