Publication number: 20170145138Abstract: The invention provides new water soluble polymers for the use in industrial processes, where large quantities of water is handled, such as sludge dewatering and papermaking. These new polymers are water soluble cross-linked block copolymers, wherein the block copolymers are cross-linked together using a cross-linking agent. Each of the block copolymers contain two different blocks, and these blocks are formed from different monomers. The blocks are linked together with a molecular spacer derived from a bifunctional initiator used during the polymerization of the blocks. The monomers used in polymerizing the blocks are different with each other and they are selected from a group consisting of N-vinylformamide, acrylic acid, acrylamide and water-soluble derivatives thereof.Type: ApplicationFiled: April 10, 2015Publication date: May 25, 2017Inventors: Asko KARPPI, Matti HIETANIEMI, Sacha LEGRAND
