- 20 - O.Z. 0050/40595 Abstract of the Disclosure: Concentrated mixtures con- tain (i) an organic solvent, (ii) a low molecular weight graft copolymer of the general formula I and (iii) a relatively high molecular weight graft copolymer of the general formula I A - E I where A is a-segment of a polymer which consists of from 70 to 100% by weight of monomer units of the general formula II and from 0 to 30% by weight of monomer units of the general formula III XHC=CR1Y II CH2=CR1Z III where R1 is H or CH3, X is H, COOH or COOR2, Y is COOH or COOR2 or X and Y are the anhydride radical CO-O-CO, Z is OCOR2, OR2, a heterocyclic 5-membered or 6-membered ring or a radical CO-B-D-R3, R2 is C1-C40-alkyl, B is O or NH, D is a C2-C10-hydrocarbon bridge and R3 is OH or N(R2)2 in which R2 has the abovementioned meaning, and E is a segment of a copolymer of ethylene with vinyl esters of aliphatic C1-C24-carboxylic acids, with or without (iv) a polymer which contains only the segments A.
