LIGNIN DERIVATIVE
PROBLEM TO BE SOLVED: To provide a lignin derivative excellent in water-reducing performance when used as a cement additive.SOLUTION: There is provided a lignin derivative having a (poly)alkylene glycol chain in the structure, wherein the lignin derivative has a skeleton represented by the formula (1). (Rto Reach independently represent H, a hydroxyl group, an alkoxy group, an amino group, a sulfonic acid group, a carboxyl group-containing group, a (poly)alkylene glycol chain-containing group, a hydrocarbon group or a direct bond with a structure derived from other phenylpropane skeletons; at least one of Rto Rrepresents a direct bond with a structure derived from other phenylpropane skeletons.)SELECTED DRAWING: None
【課題】セメント添加剤として用いた場合の減水性能に優れたリグニン誘導体の提供。【解決手段】構造中に（ポリ）アルキレングリコール鎖を有するリグニン誘導体であって、該リグニン誘導体は、式（１）で表される骨格を有するリグニン誘導体。（Ｒ１〜Ｒ６は各々独立にＨ、水酸基、アルコキシ基、アミノ基、スルホン酸基、カルボキシル基含有基、（ポリ）アルキレングリコール鎖含有基、炭化水素基、又は、他のフェニルプロパン骨格由来の構造との直接結合；Ｒ１〜Ｒ６のうち少なくとも１つは、他のフェニルプロパン骨格由来の構造との直接結合）【選択図】なし
