    摘要： The present invention is directed to a method for producing a copolymer and a copolymer product of the method. The copolymer is prepared by a controlled radical polymerization process, typically an atom transfer radical polymerization process, in which polymerizable alkene monomers are polymerized in the presence of a halogenated polyolefin macroinitiator. The copolymer product of this process is useful in a film-forming composition that adheres strongly to polyolefinic substrates and to which non-polyolefinic film-forming compositions strongly adhere. The copolymer can be applied to a substrate in an adhesion-promoting layer or can be incorporated into a film-forming composition, such as a primer, that contains additional resinous compounds.

    摘要： A pigment dispersion comprising pigment, an aqueous carrier selected from water and a mixture of water and at least one organic solvent, and a pigment dispersant is described. The pigment dispersant is prepared by polymerizing (i) at least one prepolymer having a radically polymerizable group, and (ii) at least one second monomer. The prepolymer is prepared by controlled radical polymerization, e.g., atom transfer radical polymerization, of at least one radically polymerizable first monomer. The second monomer forms a polymeric backbone segment of the pigment dispersant, and the prepolymer forms polymeric segments that are pendent to the backbone. The backbone segment of the pigment dispersant in hydrophobic, while at least a portion of each pendent polymeric segment is hydrophilic.

    摘要： Block copolymers containing at least two blocks are provided and comprise: (a) a first block containing residues of at least one first ethylenically unsaturated radically polymerizable monomer that is free of hydroxy functionality, e.g., 2-ethylhexyl methacrylate, and a minor amount of at least one hydroxy functional ethylenically unsaturated radically polymerizable monomer, e.g., hydroxypropyl methacrylate; and (b) a second block containing residues of at least one second ethylenically unsaturated radically polymerizable monomer that is free of hydroxy functionality, e.g., iso-butyl methacrylate, and a minor amount of at least one hydroxy functional ethylenically unsaturated radically polymerizable monomer. The calculated Tg of the second monomer of the block copolymer is at least 20° C. greater than the calculated Tg of the first monomer.
