Title (EN) VINYL COPOLYMER
(FR) COPOLYMÈRE DE VINYLE
(JA) ビニル共重合体
Abstract:
(EN) Provided is a novel vinyl copolymer useful, for example, as a fluidity maintenance agent for maintaining the fluidity of a hydraulic cement composition. A vinyl copolymer having a weight-average molecular weight of 8000-200,000 and a proportion of 1-99 mol% of a specific structural unit A that has a carboxyl group, and 1-99 mol% of a specific structural unit B having a polyalkylene glycol residue (total 100 mol%) in the total structural units.
(FR) L'invention fournit un nouveau copolymère de vinyle qui se révèle avantageux en tant qu'agent de maintien de fluidité afin de maintenir la fluidité d'une composition de ciment hydraulique, par exemple. Plus précisément, l'invention concerne un copolymère de vinyle de masse moléculaire moyenne comprise entre 8000 et 200000 qui possède une proportion de 1 à 99% en moles d'une unité constitutive (A) spécifique ayant un groupe carboxyle, et de 1 à 99% en moles d'une unité constitutive (B) spécifique ayant un résidu de glycol de polyoxyalkylène (au total 100% en moles) pour l'ensemble de ses unités constitutives.
(JA) 例えば水硬性セメント組成物の流動性を保持するための流動性保持剤として有用な、新規のビニル共重合体を提供する。 全構成単位中にカルボキシル基を有する特定の構成単位Aを1~99モル%及びポリアルキレングリコール残基を有する特定の構成単位Bを1~99モル%(合計100モル%)の割合で有する重量平均分子量8000~200000のビニル共重合体とした。
