  • Publication number: 20150376472
    Abstract: A process for preparing crosslinkable oligomers comprising reacting at least one monomer having the structure: VHC?CHX, wherein more than 60% of such monomer or monomers has at least one crosslinkable functional moiety, and at least one monomer having the structure: WHC?CYZ at certain molar ratios and reaction conditions, in which V, X, W, and Z are predefined in the text. Curable coatings, sealants, and adhesives utilizing such crosslinkable oligomers and block, branched, star and comb-like graft crosslinkable copolymers derived from such crosslinkable oligomers are also disclosed.

  • Patent number: 6541571
    Abstract: A process for compatibilizing at least two mutually incompatible polymers, and a blended resins thereof, wherein said process comprises: (i) adding to at least one of the polymers an effective amount of a compatibilizing dispersant, wherein said dispersant is the polymerization reaction product of a mixture of monomers consisting essentially of: (a) from about 10% to about 40% by weight styrene; and (b) from about 10% to about 55% by weight of at least one alkyl methacrylate monomer having 1 to 8 carbon atoms in the alkyl group; and (c) from about 10% to about 55% by weight of at least one alkyl methacrylate monomer having greater than 8 carbon atoms in the alkyl group; and (d) from about 5% to about 25% by weight of at least one alkyl acrylate monomer having from 1 to 18 carbon atoms in the alkyl group; and (e) from about 7% to about 25% by weight of at least one hydroxy-functional ethylenically unsaturated monomer having a molecular weight of less than 2000; and (f) from about 0.

  • Patent number: 6387167
    Abstract: An ink composition, said ink composition comprising: (a) from about 10% to about 40% by weight styrene; and (b) from about 10% to about 55% by weight of at least one alkyl methacrylate monomer having 1 to 8 carbon atoms in the alkyl group; and (c) from about 10% to about 55% by weight of at least one alkyl methacrylate monomer having greater than 8 carbon atoms in the alkyl group; and (d) from about 5% to about 25% by weight of at least one alkyl acrylate monomer having from 1 to 18 carbon atoms in the alkyl group; and (e) from about 7% to about 25% by weight of at least one hydroxy-functional ethylenically unsaturated monomer having a molecular weight of less than 2000; and (f) from about 0.1% to about 15% of a compound providing an amine functional moiety, said compound being an acrylate or methacrylate compound containing amino groups, copolymerizable with (a), (b), (c), (d), and (e); wherein the dispersant is substantially free of acid functionality.
