  • Patent number: 11897995
    Abstract: The presently claimed invention is directed to a copolymer obtained by reacting at least one isocyanate (A) comprising at least one allophanate group and at least one active double bond with at least one isocyanate reactive component (B) to form an intermediate product (C); and reacting the intermediate product (C) with at least one active double bond reactive component (D) to obtain the copolymer which can be used as dispersant. The at least one isocyanate reactive component (B) is selected from the group consisting of monofunctional polyether amine (B1), monofunctional polyether alcohol (B2), C6-C30 monofunctional alcohol (B3) and monofunctional polyester alcohol (B4).

  • Publication number: 20230383043
    Abstract: Disclosed herein is a process of producing a polymeric dispersion by free radical emulsion polymerization of a monomer composition including ethylenically unsaturated monomers in the presence of a block copolymer. The block copolymer has a first block including at least 80 wt.-% units of alkyl acrylate and a second block including units of an ethylenically unsaturated monomer with sulfonic acid groups. Either the first or the second block is connected with a nitroxyl radical. The polymeric dispersion is obtainable by the disclosed process, and the block copolymer is used in the process. Further disclosed herein is a method of using the block copolymer as an emulsifying agent for free radical emulsion polymerization.

  • Publication number: 20230192962
    Abstract: The presently claimed invention relates to an amine-modified polymer and method for preparation thereof. The presently claimed invention is also directed to the use of the polymer as dispersant in ink and coating compositions. Polyacrylate polymer is obtained by controlled free radical polymerization of a mixture comprising at least one acrylate monomer. The post-modification of polyacrylate polymers yields amine-modified polymers that provide improved viscosity parameters, without sacrificing the advantages of a well-defined polymer structure.
