Procedure

A formulation consisting of 70 kg of cellulose, 20 kg of potassium caseinate and 10 kg of polymer d2) having a content of N-vinylimidazole (Vl) of 90% by weight, a content of N-vinylpyrrolidone (VP) of 7% by weight and a content of N,N′-divinylethyleneurea (DVEU) of 3% by weight was prepared by dissolving the potassium caseinate in 400 l of water at 60° C. and suspending the cellulose therein. The suspension was atomized at 185° C. at 70 bar via a single-component nozzle and the polymer was injected into the atomization zone.
