Title:
成形用環状オレフィン系樹脂組成物、成形体および樹脂
Document Type and Number:
Japanese Patent JP6906605
Kind Code:
B2
Abstract:
Provided is a cyclic olefin-based resin composition for molding containing a resin (A) which contains a structural unit (a1) derived from an α-olefin and a structural unit (a2) derived from a cyclic olefin, have a glass transition temperature in both a region equal to or lower than 50°C and a region equal to or higher than 125°C in a case where the composition is subjected to differential scanning calorimetry, and has a dispersity within a range of 1.0 to 1.6 measured by gel permeation chromatography. Also provided is a molded product formed of the composition. The resin (A) has a structural unit (a1) derived from an α-olefin and a structural unit (a2) derived from a cyclic olefin, has a glass transition temperature in both a region equal to or lower than 50°C and a region equal to or higher than 125°C in a case where the resin is subjected to differential scanning calorimetry, and has a dispersity within a range of 1.0 to 1.6 measured by gel permeation chromatography.
