Abstract: Cross-linked cationic polymers are prepared by alkylating a polyaminoalide with 5 to 30 mole percent, relative to the amount of nitrogen available for alkylation, of a quaternary ammonium alkylating agent and cross-linking the resulting alkylated polyaninoamide with a molar amount of epichlorohydrin corresponding to the non-quaternized nitrogen content. The cross-linked cationic polymers are suitable for use as wet-strength resins in the treatment of paper.

Abstract: Wheat protein hydrolyzates are produced by hydrolyzing a wheat protein-containing starting material, preferably a wheat protein isolate having a protein content of 70 to 90%, with a proteinase such as a serine protease at a pH of 2 to 5, then with a proteinase at a pH of 8 to 10 and finally with a peptidase at a pH of 6 to 7. The hydrolysis steps are preferably at a temperature below the gelatinization temperature of carbohydrate present in the protein. Each hydrolysis may be carried out for 1 to 24 hours at a temperature of 40 to 70.degree. C. To reduce traces of unwanted color formers, an adsorbent such as silica gel, aluminum oxide or activated carbon may be present during the hydrolysis steps. Aqueous wheat protein hydrolyzate solutions are obtained and, if required, may be concentrated, for example using falling film evaporators. The hydrolyzates have an average molecular weight in the range of 100 to 30,000, preferably 2,000 to 5,000, and a solids content of around 5 to 50%.
