Abstract:
(EN) The present invention pertains to: a polyacrylamide-based papermaking additive including an aldehyde-functionalized polyacrylamide which has excellent paper-strengthening effects and provides satisfactory water-filterability; and a method for producing paper by using the polyacrylamide-based papermaking additive. The polyacrylamide-based papermaking additive includes an aldehyde-functionalized polyacrylamide (A) which is a dialdehyde compound adduct of an amphoteric polyacrylamide copolymer (a) including, as polymer structural units, (meth)acrylamide, a cationic vinyl monomer, an anionic vinyl monomer, and a (meth)allyl-group-including monomer, and which is characterized by satisfying various conditions.
(FR) La présente invention concerne : un additif de fabrication de papier à base de polyacrylamide comprenant un polyacrylamide à fonctionnalité aldéhyde qui présente d'excellents effets de renforcement du papier et confère une filtrabilité à l'eau satisfaisante ; et un procédé de fabrication de papier à l'aide de l'additif de fabrication de papier à base de polyacrylamide. L'additif de fabrication de papier à base de polyacrylamide comprend un polyacrylamide à fonctionnalité aldéhyde (A) qui est un adduit de composé dialdéhyde d'un copolymère polyacrylamide amphotère (a) comprenant, en tant qu'unités structurales polymères, un (méth)acrylamide, un monomère de vinyle cationique, un monomère de vinyle anionique, et un monomère comprenant un groupe (méth)allyle, et qui est caractérisé en ce qu'il satisfait diverses conditions.
(JA) 本発明は、紙力増強効果が優れ、濾水性が良好なアルデヒド官能化ポリアクリルアミドを含むポリアクリルアミド系製紙用添加剤、及び、該ポリアクリルアミド系製紙用添加剤を用いた紙の製造方法に関するものであって、(メタ)アクリルアミド、カチオン性ビニルモノマー、アニオン性ビニルモノマー、および(メタ)アリル基を有するモノマーをポリマー構成単位として有する両性ポリアクリルアミド共重合体(a)のジアルデヒド化合物付加物である、諸条件を満足することを特徴とする、アルデヒド官能化ポリアクリルアミド(A)を含むポリアクリルアミド系製紙用添加剤である。
