Sizing agents comprised of dispersed synthetic polymers in an aqueous solution are provided, as well as methods for making these sizing agents and methods for using these sizing agents to size paper. The polymers are prepared by copolymerizing styrene which optionally may be substituted and certain acrylates in the presence of a stabilizing agent. Improved sizing is obtained by including recurring units of methyl acrylate, ethyl acrylate, and/or propyl acrylate in the synthetic polymers.
L'invention concerne des agents de collage composés de polymères synthétiques dispersés dans une solution aqueuse, ainsi que des procédés de fabrication de ces agents de collage et des procédés d'utilisation de ces derniers pour le collage du papier. Les polymères sont préparés par copolymérisation de styrène, qui peut éventuellement être substitué, et de certains acrylates en présence d'un agent stabilisant. Un collage amélioré est obtenu par incorporation de motifs récurrents d'acrylate de méthyle, d'acrylate d'éthyle et/ou d'acrylate de propyle dans les polymères synthétiques.
