Use of grafted sma copolymers in liquid compositions

Abstract

The subject of the invention is the use of a grafted copolymer derived from the grafting: —of an SMA copolymer (II) derived from the copolymerization of at least two monomers, (i) the first monomer being chosen from styrene and its derivatives and (ii) the second monomer including at least one anhydride function, —with either (iii) M-R—X molecules (I) including at least one pattern (M) chosen from patterns (1) to (4): formula (I), with A=oxygen, sulfur or NH; and including at least one chemical function (X) chosen from among halogen, a primary or secondary amine function, an alcohol function, a thiol function, a carboxylic acid function or a derivative of said function and an epoxy function, the pattern (M) and said function (X) being connected by a rigid or flexible chain (R); namely (iv) molecules belonging to the family of triazoles; used as the majority composition or additive of liquid compositions intended to be applied in or on sheets of paper or cardboard, onto hard surfaces, on leather or on textiles.
