Abstract
(EN) The present invention provides an epoxy resin and an epoxy resin composition, cured products of which have excellent low water absorption and high elasticity. This epoxy resin is represented by formula (1). (In formula (1), n is the number of repetitions and the average thereof is 1<n<20. R represents a substituent represented by formula (2). Each p represents a real number of 0 to 4, and the average value of p is 0.5 to 1.5.) (In formula (2), * represents the portion bonded to an aromatic ring in formula (1). X represents a hydrogen atom or a hydrocarbon group having 1-6 carbon atoms. q represents a real number of 0 to 5.)
(FR) La présente invention concerne une résine époxy et une composition de résine époxy, des produits durcis ayant une excellente propriété d'absorption d'eau faible et une élasticité élevée. Cette résine époxy est représentée par la formule (1). (Dans la formule (1), n est le nombre de répétitions et la moyenne de celles-ci est 1<n<20. R représente un substituant représenté par la formule (2). Chaque p représente un nombre réel de 0 à 4, et la valeur moyenne de p est de 0,5 à 1,5.) (Dans la formule (2), * représente la partie liée à un cycle aromatique dans la formule (1). X représente un atome d'hydrogène ou un groupe hydrocarboné ayant de 1 à 6 atomes de carbone. q représente un nombre réel de 0 à 5.)
(JA) 本発明は、その硬化物が低吸水性、高弾性に優れるエポキシ樹脂、エポキシ樹脂組成物を提供する。 下記式(1)で表されるエポキシ樹脂。 (式(1)中、nは繰り返し数であり、その平均値は1<n<20である。Rは下記式(2)で表される置換基を示す。pはそれぞれ0~4の実数を表し、pの平均値は0.5~1.5である。)(式(2)中、*は式(1)の芳香環への結合部分を表す。Xは水素原子または炭素数1~6の炭化水素基を示す。qは0~5の実数を表す。)
