Abstract: The present invention relates to starch which is modified with at least one cationic polymer(P), and a method for producing same which is characterized in that: a) an anionically modified starch (A) is reacted with the cationic polymer (P); or that (b) a native starch (B) or a non-anionically modified starch (C) is reacted with the cationic polymer (P) in the presence of an anionic modifier (M). The invention also relates to the use of said polymer-modified starches.

Abstract: The invention relates to a method for producing alkyl ketene dimers by reacting carboxylic acid chlorides with tertiary amines in a molar ratio of between 1: 1 and 1: 1.6 at temperatures of between 65 and 150 ~C and with a residence time of between 1 and 30 mins in the absence of solvents. Said reaction partners are intensively mixed and the alkyl ketene dimers are separated from the reaction mixture.
