COPOLYMERE ALCALISOLUBLE ASSOCIATIF DIOL ET SON UTILISATION COMME AGENT EPAISSISSANT POUR LE COUCHAGE PAPIER

摘要

The invention concerns an associative alkaline soluble copolymer characterised in that said copolymer comprises about (A) 15 to 60 wt.% of at least one monocarboxylic or dicarboxylic alpha , beta monomer, ethylenically unsaturated in C3-C8; (B) 15 to 80 wt.% of at least a non-ionic and copolymerisable alpha , beta monomer ethylenically unsaturated in C2-C12; (C) 1 to 20 wt.% of a non-ionic biphilic monomer ethylenically unsaturated of general formula (I); (D) 1 to 10 wt.% of an ethylenically unsaturated monomer bearing at least two vicinal hydroxyl functions or a group precursor of said functions. The invention also concerns a method for preparing said polymer and its application in paper coating.
