Title:
COPOLYMER AND RESIN COMPOSITION CONTAINING COPOLYMER
Document Type and Number:
WIPO Patent Application WO/2024/080287
Kind Code:
A1
Abstract:
Provided is a copolymer which can be inhibited from taking a color even through heating. The copolymer comprises a constituent unit (A) derived from 1,1-dicyanoethylene and a constituent unit (B) derived from a compound represented by general formula (I): CH2=CR1R2, and is characterized by including the following four kinds of triads (U-1) to (U-4) each composed of the constituent unit (A) and the constituent unit (B): (U-1), (A)-(A)-(A); (U-2), (A)-(A)-(B); (U-3), (B)-(A)-(A); and (U-4), (B)-(A)-(B), the total content of (U-2) and (U-3) in all the four kinds of triads being 9.0 mol% or less.
