Abstract: Amphiphilic graft copolymers are prepared by grafting a pre-formed graft base polymer comprising at least 5% by weight of units of formula (I)where R1 and R2 are independently H or C1 to C6 alkyl groups. The monomer grafted to the pre-formed graft base polymer is at least one of styrene or a C1 to C2 alkylstyrene, and optionally other monoethylenically unsaturated monomers. At least 5 mole % of the groupsare cleaved from the grafted copolymer thus formed.

Abstract: The invention relates to a method for fractionation of water soluble or dispersible synthetic polymers containing amino groups with a broad molar mass distribution by means of ultrafiltration. The polymer solution or dispersion which is to be fractionated is continuously fed into an utltrafiltration circuit comprising at least one ultrafiltration unit and the retentate with a narrower molar mass distribution and the permeate are continuously discharged in such a way that the ultrafiltration circuit is placed in a substantially stationary state. The invention also relates to polymers which can be obtained according to the inventive method and to the use thereof.
