    摘要： The present invention is directed to copolymers, which are polymerization products of: (i) a monomer having alpha-olefinic functionality; (ii) a monomer different from (i) having active hydrogen functionality; and (iii) a monomer different from (ii) having acrylic functionality. The molar ratio of the monomer (i) having alpha-olefinic functionality to the monomer (iii) having acrylic functionality is less than 1:1, and the conversion of the monomer (i) having alpha-olefinic functionality during polymerization is greater than 90%. When monomers having methacrylic functionality are used to prepare the copolymer, the molar ratio of the monomer (iii) having acrylic functionality to the monomers having methacrylic functionality is greater than 2:1. Also disclosed are curable film-forming compositions comprising the copolymers.

    摘要： A composition that includes a non-gelled copolymer that contains residues having structural units (I): where n is an integer from 1 to 10,000; R1 is linear or branched C1 to C4 alkyl; R2 is selected from the group consisting of methyl, linear, cyclic or branched C2 to C20 alkyl, alkenyl, aryl, alkaryl and aralkyl, and R3 is a group resulting from a post polymerization reaction selected from transesterification, transamidification and hydrolysis with a compound selected from hydroxy functional compounds and amine functional compounds. The composition may contain co-reactive functional groups and may be a thermosetting composition. A substrate may be coated with the thermosetting composition singly or as part of a multi-layer composite coating that includes a base coat layer and a substantially pigment free top coat layer.

    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 has core and arm star-type architecture, and is prepared by controlled radical polymerization, e.g., atom transfer radical polymerization, using (i) arm-core, (ii) arm-core-arm, (iii) core-arm, or (iv) concurrent core and arm methods. The arms of the pigment dispersant each have hydrophobic and hydrophilic polymeric chain segments.
