(ZH) 一种水溶性固体聚丙烯酰胺及其用途
Abstract:
(EN) Water-soluble solid polyacrylamide formed by chain polymerization copolymerization of at least four types of monomers, i.e., a non-ionic monomer A, a non-ionic monomer B, a cationic monomer, and a anionic monomer. Use of the water-soluble solid polyacrylamide in reinforcement and/or modification of a natural fiber material or a semi-synthetic fiber material.
(FR) L'invention concerne un polyacrylamide solide hydrosoluble formé par copolymérisation par polymérisation en chaîne d'au moins quatre types de monomères, à savoir, un monomère non ionique A, un monomère non ionique B, un monomère cationique et un monomère anionique. L'invention concerne également l'utilisation du polyacrylamide solide hydrosoluble dans le renforcement et/ou la modification d'un matériau fibreux naturel ou d'un matériau fibreux semi-synthétique.
