Abstract
(EN)
Provided are a copolymer having excellent storage stability that cures at a relatively low temperature and has excellent solvent resistance of the cured product, a curable resin composition that includes the copolymer, and a cured product thereof. The copolymer includes a structural unit (A) derived from an unsaturated carboxylic acid or an anhydride thereof and a structural unit (B) derived from an epoxy compound represented by formula (b1) (in the formula, Rb1 represents a hydrogen atom or a C1-7 alkyl group. Rb2 represents a divalent hydrocarbon group that optionally includes a hetero atom. Rb3 represents a divalent organic group having two or more epoxy groups.).
(FR)
L'invention concerne un copolymère ayant une excellente stabilité au stockage qui durcit à une température relativement basse et confère une excellente résistance aux solvants au produit durci, une composition de résine durcissable qui comprend le copolymère, et un produit durci obtenu à partir de celle-ci. Le copolymère comprend un motif structural (A) dérivé d'un acide carboxylique insaturé ou d'un anhydride de celui-ci et un motif structural (B) dérivé d'un composé époxy représenté par la formule (b1) (dans la formule, Rb1 représente un atome d'hydrogène ou un groupe alkyle en C1-7. Rb2 représente un groupe hydrocarboné divalent qui comprend éventuellement un hétéroatome. Rb3 représente un groupe organique divalent ayant deux groupes époxy ou plus.).
(JA)
保存安定性に優れ、比較的低い温度でも硬化し、且つ硬化物の耐溶剤性が優れる共重合体、該共重合体を含む硬化性樹脂組成物、及びその硬化物を提供する。不飽和カルボン酸又はその無水物に由来する構成単位(A)と、下記式(b1)(式中、Rb1は、水素原子又は炭素数1~7のアルキル基を示す。Rb2は、ヘテロ原子を含んでいてもよい2価の炭化水素基を示す。Rb3は、2以上のエポキシ基を有する2価の有機基を示す。) で表されるエポキシ化合物に由来する構成単位(B)とを含む共重合体。
