Title (EN) METHOD FOR PRODUCING MODIFIED CONJUGATED DIENE-BASED RUBBER
(FR) PROCÉDÉ DE PRODUCTION D’UN CAOUTCHOUC À BASE DE DIÈNE CONJUGUÉ MODIFIÉ

Abstract:
(EN) Provided is a method for producing a modified conjugated diene-based rubber, the method comprising: a first step, in which an alkali-metal-containing aromatic compound having, in the molecule, two carbon atoms each directly bonded to both an alkali metal atom and the aromatic ring is used as a polymerization initiator to polymerize one or more monomers comprising a conjugated diene compound, thereby obtaining a conjugated diene-based rubber having an active terminal; a second step, in which the conjugated diene-based rubber having an active terminal is subjected to a coupling reaction using a bifunctional coupling agent; and a third step, in which the active terminal of the conjugated diene-based rubber having undergone the coupling reaction is reacted with a modifier having, in the molecule, one atom or reactive group capable of reacting with the active terminal, thereby obtaining a modified conjugated diene-based rubber.
(FR) L'invention concerne un procédé de production d'un caoutchouc à base de diène conjugué modifié, le procédé comprenant : une première étape, dans laquelle un composé aromatique contenant un métal alcalin ayant, dans la molécule, deux atomes de carbone chacun directement lié à la fois à un atome de métal alcalin et à l'anneau aromatique est utilisé en tant qu'initiateur de polymérisation pour polymériser un ou plusieurs monomères comprenant un composé diène conjugué, ce qui permet d'obtenir un caoutchouc à base de diène conjugué ayant une terminaison active ; une deuxième étape, dans laquelle le caoutchouc à base de diène conjugué ayant une terminaison active est soumis à une réaction de couplage à l'aide d'un agent de couplage bifonctionnel ; et une troisième étape, dans laquelle la terminaison active du caoutchouc à base de diène conjugué ayant subi la réaction de couplage est mise à réagir avec un modificateur ayant, dans la molécule, un atome ou un groupe réactif susceptible de réagir avec la terminaison active, ce qui permet d'obtenir un caoutchouc à base de diène conjugué modifié.
(JA) 重合開始剤として、アルカリ金属原子と芳香環とに直接結合した炭素原子を、1分子中に2個有するアルカリ金属化芳香族化合物を用いて、少なくとも共役ジエン化合物を含んでなる単量体を重合し、活性末端を有する共役ジエン系ゴムを得る第1工程と、2官能のカップリング剤を用いて、前記活性末端を有する共役ジエン系ゴムのカップリング反応を行う第2工程と、前記カップリング反応を行った共役ジエン系ゴムの活性末端に、前記活性末端と反応することができる原子または反応基を1分子中に1個有する変性剤を反応させて、変性共役ジエン系ゴムを得る第3工程と、を備える変性共役ジエン系ゴムの製造方法を提供する。
