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: Paper, board and cardboard having high dry strength are produced by the addition of cationic, anionic and/or amphoteric starch as dry strength agents to the paper stock and drainage of the paper stock with sheet formation in the presence of cationic polymers as retention aids for starch, and cationic polymeric retention aids are used for increasing the retention of dry strength agents comprising cationic, anionic and/or amphoteric starch in the production of paper, board and cardboard.

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.

Date Jul. 9, 1998Paper is produced by draining a paper stock containing process chemicals on a paper machine, a main stream of the paper stock and a dilution stream which consists of white water, contains at least 5% by weight of the process chemicals and amounts to 5-35% by volume of the total head box feed being fed via a head box to the paper machine wire. The papers thus produced have an excellent formation profile and an outstanding ash distribution.
