    摘要： A copolymer having utility in coating compositions comprises the addition polymerization product of an alpha-olefin monocarboxylic acid having at least 8 carbon atoms (articularly undecylenic acid) and a mono- or di-ester of an unsaturated dicarboxylic acid or anhydride (e.g., dialkyl maleate). The copolymer may be provided with hydroxy functionality by reacting the carboxylic acid functionality with an epoxy compound to permit use in curable coatings. Alternatively the copolymer may be base neutralized to serve as a surfactant in aqueous dispersion polymerization.

    摘要： A pigment dispersion which includes a pigment, an aqueous carrier and a pigment dispersant. The pigment dispersant is prepared by controlled radical polymerization initiated in the presence of a monomeric initiator having at least two radically transferable groups. The pigment dispersant has at least one of the following polymer chain structures: &phgr;-[(G)p—(E)s—T]z and &phgr;-[(E)3—(G)p—T]z where G is a hydrophobic residue of at least one radically polymerizable ethylenically unsaturated monomer; E is a hydrophilic residue of at least one radically polymerizable ethylenically unsaturated monomer; &phgr; is a residue of or derived from the initiator, and is free of the radically transferable group; T is or is derived from the radically transferable group of the initiator; z is 2 to 10; p and s are at least one and are selected such that the pigment dispersant has a number average molecular weight of at least 500.

    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.

    摘要： A polyurethane polyanhydride oligomer is disclosed as well as a process for its preparation. The process involves the following steps:(a) reacting a hydroxyl functional 2,4-dienoate ester with a polyisocyanate under conditions sufficient to react essentially all of the isocyanate groups to form a polyurethane polyene; and(b) reacting by Diels Alder addition the unsaturated double bonds of the polyurethane polyene with an unsaturated polycarboxylic acid anhydride containing material. Also disclosed is a curable composition containing hydroxyl functional material and the aforedescribed polyurethane polyanhydride oligomer.
