Abstract: Disclosed are amphiphilic graft polymers in which the graft base is a polymer containing at least 5 wt % of units of formula (I) and optionally units of formula (II), R1, R2 being H or C1-C6 alkyl, wherein (a) styrene, C1-C2 alkylstyrene and/or vinyltoluene and optionally (b) other monoethylenically unsaturated monomers which can be copolymerized therewith are grafted onto the graft base in a weight ratio of between 1: 99 and 99: 1, and wherein the group (c) is optionally partially or completely cleaved off the graft polymers, forming amino groups. Also disclosed are processes for preparing and using the amphiphilic graft polymers as consolidating agents for paper, as fixing agents for disruptive water-soluble and water-insoluble agents in paper manufacture, as dispersants for inorganic and organic pigments, dyes, concrete and plant-protecting agents, as detergent additives, as coating material for fertilisers and plant-protecting agents, as floor-maintenance agents, as protective colloids for aqueous polymer dispersions, as thickeners for cosmetic formulations, as conditioners for skin-care agents and as a component of hair-cosmetic preparations and cosmetic preparations for oral hygiene.

Abstract: In a cationic modification process for starch, starch is reacted with polymers that contain amino and/or ammonium groups in an aqueous medium at temperatures from 115 to 180 ·C under an increased pressure and in the absence of oxidisers, polymerisation initiators and alkali. The reaction is conducted so that maximum 10% by weight starch has its molar weight reduced. Also disclosed is the use of the thus obtained reaction products as dry strength agents for paper.
