Title:
CYCLIC OLEFIN RESIN COMPOSITION FOR MOLDING, MOLDED BODY, AND RESIN
Document Type and Number:
WIPO Patent Application WO/2018/181781
Kind Code:
A1
Abstract:
Provided are: a cyclic olefin resin composition for molding, the composition containing a resin (A) which has a structural unit (a1) derived from α-olefin and a structural unit (a2) derived from cyclic olefin, has glass transition points in both a 50°C or lower region and a 125°C or higher region as measured by differential scanning calorimetry, and has a degree of dispersion in the range of 1.0-1.6 as measured by gel permeation chromatography; and a molded body produced from this composition. Also provided is a resin (A) which has a structural unit (a1) derived from α-olefin and a structural unit (a2) derived from cyclic olefin, has glass transition points in both a 50°C or lower region and a 125°C or higher region as measured by differential scanning calorimetry, and has a degree of dispersion in the range of 1.0-1.6 as measured by gel permeation chromatography.
