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: Method of modifying cleaned or chemically pre-treated metal surfaces with aq. solns. of organic polymers contg. amino gps. In an example, a sample of Mn-modified, low Zn content, phosphatised steel that had been cleaned with water was immersed for 60s in a 0.1 wt.% aq. polyvinylamine soln. at 50 deg.C, then after drying in air the sample was immersed for 5s in deionised water and then after drying in air again the sample was cathodically electro-plated in a bath according to the comparative example in German patent application DE4208056-A2. The sample was plated at 320-380 V to give a 23 micron thick coating, and then fired for 25 mins. at 165 deg.C. A 0.1 mm wide incision was made in the lacquered sample, extending down to the metal surface and the sample was sprayed for 15 days with aq. NaCl soln. (5 wt.%) at 40 deg.C (salt water spray test), whilst another sample was immersed for 10 days in an aq. NaCl soln. (5 wt.%) warmed to 55 deg.C (salt water soak test). No rust was observed for the soak test, whilst only a slight amt. of rust was observed for the spray test.
