Title (EN) METHOD FOR PRODUCING (METH)ACRYLIC ACID ESTER POLYMER
(FR) PROCÉDÉ DE PRODUCTION DE POLYMÈRE D’ESTER D’ACIDE (MÉTH)ACRYLIQUE
(JA) (メタ)アクリル酸エステル重合体の製造方法
Abstract:
(EN) The present invention addresses the problem of providing a method for producing a (meth)acrylic acid ester polymer with which it is possible to polymerize even (meth)acrylic acid ester monomers having no donor group at the β position of the ester moiety while maintaining high living properties. (Meth)acrylic acid ester monomers are polymerized using an organic oxy alkali metal compound represented by the formula R-OM (in the formula, M is an alkali metal cation, R is an active hydrogen-free organic group) in the presence of a hindered amine compound.
(FR) La présente invention résout le problème de fourniture d’un procédé de production d’un polymère d’ester d’acide (méth)acrylique avec lequel il est possible de polymériser même des monomères d’ester d’acide (méth)acrylique n’ayant pas de groupe donneur à la position β du fragment ester tout en maintenant des propriétés vivantes élevées. Des monomères d'esters d'acide (méth)acrylique sont polymérisés au moyen d'un composé d’oxyde de métal alcalin organique représenté par la formule R-OM (dans la formule, M est un cation de métal alcalin, R est un groupe organique sans hydrogène actif) en présence d'un composé d’amine encombrée.
(JA) 本発明の課題は、エステル部のβ位に供与基がない(メタ)アクリル酸エステルモノマーについても高いリビング性を保持して重合することができる、(メタ)アクリル酸エステル重合体の製造方法を提供することである。 ヒンダードアミン化合物の存在下、式 R-OM(式中、Mはアルカリ金属カチオンであり、Rは、活性水素を有しない有機基である。)で表される有機オキシアルカリ金属化合物を用いて(メタ)アクリル酸エステルモノマーを重合する。
