Date Nov. 30, 1995A process for the preparation of a stable water-in-oil emulsion of a hydrolyzed polymer of an N-vinyl amide of the formula (I) in which R and R1 denote H or C1-C6 alkyl, by the polymerization of a compound of the formula I alone or in admixture with another ethylenically unsaturated monomer in the presence of a polymerization initiator and emulsifier in the form of a water-in-oil emulsion, to form a water-in-oil polymeric emulsion, followed by hydrolysis of the polymer in the form of the water-in-oil polymeric emulsion in the presence of an acid or base and from 1 to 30 wt %, based on the polymer, of an emulsifier, the emulsifier used being a mixture of (a) from 5 to 95 wt % of a block or graft copolymer of the structure (A-B)m, (A)-B or (B)-A, in which in each case (a) from 5 to 95 wt % of a block or graft copolymer of the structure (A-B)m, (A)nB or (B)nA, in which in each case A is a hydrophobic homopolymer or copolymer having a degree of polymerization of at least 3, B is a hydrophilic homopolymer or copolymer having a degree of polymerization of at least 3, m is equal to or greater than 1, and n is equal to or greater than 2, and (b) from 5 to 95 wt % of another water-in-oil emulsifier having a molar mass below 1000 g/mol.

Date Sep. 28, 1995Graft polymers which contain N-vinyl units and in which the grafting base is a polymer which contains in each case at least 5% by weight of units of the formulae (I) (II) where R1 and R2 are each H or C1-C6-alkyl, monoethylenically unsaturated monomers are grafted onto the grafting base in a weight ratio of from 100:1 to 1:100, and which have K values of at least 7 (determined according to H. Fikentscher in 5% strength by weight aqueous solution at 25 DEG C. and pH 7), are prepared by polymerization of monoethylenically unsaturated monomers in the presence of polymers which in each case contain at least 5% by weight of units of the formulae I and/or II as the grafting base in a weight ratio of from 100:1 to 1:100, and are used as dispersants for pigments, as additives for detergents and cleaning agents, and strength agents for paper and as soil stabilizers and for fertilizer compaction.

    Abstract: The invention concerns the use, as dispersants for aqueous pigment suspensions, of partially esterified copolymers obtained by the copolymerization of (a) at least one C4 to C28 olefin and (b) ethylenically unsaturated dicarboxylic acid anhydrides with 4 to 8 C-Atoms in the molar ratio of 1:0.5 to 1:2 and the subsequent partial esterification of the copolymer with reaction products of (A) C1 to C30 alcohols, C8 to C22 fatty acids, C1 to C12 alkylphenols or secondary C2 to C30 amines and (B) at least one C2 to C4 alkylene oxide or tetrahydrofuran in the molar ratio (A):(B) of 1:2 to 1:200, and hydrolysis of the anhydride groups in the copolymer to give carboxyl groups, the partial esterification of the copolymer being carried out to an extent such that 1 to 50 % of the carboxyl groups in the copolymer are esterified. The invention also concerns pigment suspensions containing such partially esterified copolymers.
