PROCESS FOR PREPARING A POLYMER DISPERSION |
摘要 |
The present invention relates to a process for preparing an aqueous polymer dispersion which comprises polymerising one or more water-soluble monomers in an aqueous solution of salt in the presence of a dispersant polymer, wherein the dispersant polymer is a co-polymer of a monomer mixture (M) comprising at least one cationic monomer and at least one monomer which is tetrahydrofurfuryl acrylate, tetrahydrofurfuryl methacrylate, or a monomer of the general formula (I) wherein R1 is hydrogen or methyl, R2 is hydrogen or C1-C2 alkyl, R3 is hydrogen, C1-C4 alkyl, phenyl, or benzyl, n= 1 to 4, and x = 1 to 50, where, the monomer mixture (M) is being substantially free from monomers which are not soluble in water and/or the dispersant polymer is obtainable by polymerising the monomer mixture (M) in a reaction medium which is substantially free from organic solvents. The invention also relates to an aqueous polymer dispersion, use of the dispersion and a process for the production of paper.
