The invention relates to a novel solvent-free method for the cationisation of a legume starch and aqueous compositions based thereon. The invention further relates to the use of the cationic starches or compositions based thereon in the paper industry and, in particular, in the wet end of a paper-making machine, as retention agent, dewatering agent and/or for improving the physical characteristics of paper, and also as an agent for reducing interfering substances contained in water circuits and/or retained on process equipment. Finally, the invention relates to the folding carton or paper thus obtained, containing at least one cationic starch originating from legumes or compositions based thereon. |
