Title:
RESIN COMPOSITION FOR PRESS MOLDING AND PRESS MOLDED BODY
Document Type and Number:
Japanese Patent JP2023112591
Kind Code:
A
Abstract:
To provide a resin composition for press molding comprising a cyclic olefin copolymer which gives a press molded body having excellent breaking strain and toughness and having less coloration and to provide a press molded body comprising the resin composition for press molding.SOLUTION: There is provided a resin composition for press molding comprising (A) a cyclic olefin copolymer and a specific amount of (B) a hindered phenol-based antioxidant, wherein the amount of the structural unit derived from the α-olefin is adjusted to be 10 mol% or more and 40 mol% or less based on the total structural units and the cyclic olefin copolymer (A) is adjusted to have two or more glass transition temperatures in the range of 0°C to 300°C as determined by solid viscoelasticity measurement in the cyclic olefin copolymer (A) by using a copolymer of a cyclic olefin monomer and an α-olefin having 3 or more and 20 or less carbon atoms as the cyclic olefin copolymer (A).SELECTED DRAWING: None
