    摘要: The present invention relates to a use of at least one homopolymer or copolymer which is obtainable by polymerizing ethylenically unsaturated monomers and which is composed of at least one structural unit (W0) or of at least two structural units (W1) and (W2) differing from one another, and also optionally of at least one other structural unit (W3) differing from (W0), (W1) and (W2), where each structural unit (W0) contains not only at least one functional group comprising at least one phosphorus atom, but also at least one functional group reactive towards an isocyanate group, each structural unit (W1) has at least one functional group having at least one phosphorus atom, each structural unit (W2) has at least one functional group reactive towards an isocyanate group, where none of the structural units (W2) comprises phosphorus atoms, and the homopolymer or copolymer contains, relative to the total quantity of the at least one structural unit (W0) within the main polymer chain of the homopolymer or copolymer, from 1 to 100 mol % of the structural units (W0) or, relative to the total quantity of the at least two structural units (W1) and (W2) within the main polymer chain of the homopolymer or copolymer, from 1 to 80 mol % of the structural units (W1) and from 1 to 80 mol % of the structural units (W2), as adhesion-strengthening additive, a coating composition containing this type of homopolymer or copolymer as component (A) and at least one binder as component (B), and also a use of this coating composition as clearcoat, on production lines, for rehabilitation, or for maintenance.

    摘要: The invention relates to comb copolymers, which can be produced from at least one diglycidyl ether (A) of general formula (I), at least one polyether monoamine (B) of the general formula Rt—[OEt]n[OPr]m[OBu]s—NH2, at least one amine (C) of the general formula Z—R1—NH2, and optionally at least one secondary amine (D) that is free of primary amino groups and is of the general formula NHTV, wherein R stands for a residue free of epoxy groups, selected from aliphatic residues, aromatic residues, and araliphatic residues; Rt stands for a residue selected from alkyl residues having 1 to 6 carbon atoms; OEt stands for an ethylene oxide residue, OPr stands for a propylene oxide residue, and OBu stands for a butylene oxide residue; n stands for a number from 0 to 100, m stands for a number from 3 to 50, and s stands for a number from 0 to 20, and n+m+s=3 to 103; R1 stands for an aliphatic, aromatic, or araliphatic hydrocarbon residue having 1 to 12 carbon atoms; Z stands for a residue free of primary and secondary amino groups and having at least one basic nitrogen atom, T and V do not contain any secondary amino groups and stand, independently of each other, for aliphatic residues having 1 to 12 carbon atoms, aromatic residues having 6 to 12 carbon atoms, or araliphatic residues having 7 to 12 carbon atoms, wherein the molar number of the sum of the primary amino groups of the polyether monoamines (B) and primary amino groups of the amines (C) divided by the molar number of the epoxy groups of the diglycidyl ethers (A) equals a value of ⅓ to ¾. The invention further relates to the production of the comb copolymers, dispersions, particulate preparations, wetting agents, and dispersants that contain the comb copolymers, to particles coated with the comb copolymers, and to the use of the comb copolymers as wetting agents and dispersants, in particular for increasing the jetness.
