Title:
CYCLIC OLEFINIC COPOLYMER, CYCLIC OLEFINIC COPOLYMER COMPOSITION AND CROSSLINKED BODY
Document Type and Number:
Japanese Patent JP2019081898
Kind Code:
A
Abstract:
To provide a cyclic olefinic copolymer that makes it possible to obtain a crosslinked body having excellent dielectric properties in a high frequency region suitable for a circuit board or the like, and also has excellent moldability, and a cyclic olefinic copolymer composition.SOLUTION: A cyclic olefinic copolymer (m) has a crosslinkable group, containing (A) a repeating unit derived from at least one olefin represented by a specific chemical formula, (B) a repeating unit derived from at least one cyclic nonconjugated diene represented by a specific chemical formula, and (C) a repeating unit derived from at least one cyclic olefin represented by a specific chemical formula. The content of the (B) cyclic nonconjugated diene-derived repeating unit is 19 mol% or more and 36 mol% or less, and the number average molecular weight Mn is 3,000 or more and 16,000 or less.SELECTED DRAWING: None
