Abstract:
(EN) [Problem] To provide a stable and efficient method for producing an oxyethylene chain-containing vinyl ether polymer where decomposition of monomers and formation of polyacetal can be suppressed. [Solution] This method for producing an oxyethylene chain-containing vinyl ether polymer includes a step of polymerizing a vinyl ether represented by formula (1) (where R1 is an alkyl group having 1 to 3 carbon atoms and n is an integer of 1 to 10) at pH 5 or more, in the presence of water as a polymerization solvent, a basic compound as an additive, and an organic azo-based compound as a radical polymerization initiator.
(FR) Le problème décrit par la présente invention est de fournir un procédé stable et efficace de production d'un polymère d'éther vinylique contenant une chaîne oxyéthylène selon lequel la décomposition des monomères et la formation de polyacétal peuvent être supprimées. La solution selon l’invention porte sur un procédé de production d'un polymère d'éther vinylique contenant une chaîne oxyéthylène comprenant une étape de polymérisation d'un éther vinylique représenté par la formule (1) (où R1 est un groupe alkyle ayant 1 à 3 atomes de carbone et n est un nombre entier de 1 à 10) à un pH de 5 ou plus, en présence d'eau en tant que solvant de polymérisation, d'un composé basique en tant qu'additif, et d'un composé azoïque organique en tant qu'initiateur de polymérisation radicalaire.
(JA) [課題]モノマーの分解やポリアセタールの生成を抑制できる、安定的かつ効率的なオキシエチレン鎖含有ビニルエーテルポリマーの製造方法の提供。 [解決手段]本発明のオキシエチレン鎖含有ビニルエーテルポリマーの製造方法は、下記式(1): (式中、Rは、炭素数1~3のアルキル基を示し、nは1~10の整数である。) で示されるビニルエーテルを、重合溶媒として水、添加剤として塩基性化合物、およびラジカル重合開始剤として有機アゾ系化合物の存在下、pH5以上で重合させる工程を含んでなる。
