    摘要: The present invention is directed to novel compounds that can serve as highly efficient initiators for controlled radical (co)polymerization processes including atom transfer radical (co)polymerization processes. These compounds include di-(trimethylolpropane)-tetra-(2-haloisobutyrate) compounds. The present invention also is directed to controlled radical (co)polymerization processes in which novel (co)polymers are prepared using the novel compounds, as well as to the novel (co)polymer products of the process.

    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 controlled radical polymerization, e.g., atom transfer radical polymerization, of a radically polymerizable monomer in the presence of a polymeric initiator having at least one radically transferable group. The polymeric initiator forms the polymeric backbone segment of the pigment dispersant, and the monomer forms polymeric segments that are pendent to the polymeric backbone segment. The pigment dispersant has comb-like architecture in which the polymeric backbone segment is hydrophobic, and at least a portion of each pendent polymeric segment is hydrophilic.

    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.
