  • Patent number: 8575256
    Abstract: A product and processes comprising urethane polymer and at least one copolymer from a hydrophobic ethylenically unsaturated C4-C30 olefins copolymerized with polar monomers such as acrylates. One process optionally utilizes an acid source to modify/catalyze the reactivity of the polar monomer and/or radically activated repeat unit from the polar monomer to promote incorporation of the ethylenically unsaturated olefin. Other processes vary depending on which polymer if formed and/or dispersed first. The hybrid copolymer shows excellent adhesion to a variety of polymeric and/or polar substrates such as polyolefins, acrylate coatings, wood, etc.

  • Publication number: 20130065468
    Abstract: The present invention discloses films, papers, and fabrics (both woven and non-woven) that are more receptive to inks or dyes. These ink/dye receptive products are made by coating the surface of the film, paper, or fabric with certain acrylate polymers. These ink/dye receptive films, papers and fabrics have the ability to then be used in making laminated and coated products. The subject invention more specifically discloses an ink/dye receptive film which is comprised of a base film which is coated with an acrylate polymer, comprised of 1 weight percent to 20 weight percent repeat units of at least one unsaturated aliphatic olefin monomer containing from 4 to 30 carbon atoms.

  • Patent number: 6784256
    Abstract: A controlled free-radical polymerization process for forming end-functionalized polymers is disclosed, particularly by degenerative iodine transfer. The end-functionalized polymers are characterized by a polydispersity less than 2.5 and a predetermined molecular weight. The end-functionalized polymers are useful as reactive intermediates in condensation polymerization, chain polymerization and heterogeneous polymerization reactions.

  • Patent number: 5143953
    Abstract: Thermal stability of vinyl halide polymers is enhanced by the use of dienophiles such as N-alkyl maleimides, and bis compounds thereof, disclosed herein. The maleimides and bis compounds thereof produce synergistic results in terms of thermal stability of vinyl halide polymers when used in conjunction with conventional metal-containing thermal stabilizers. Environmental concerns are abated and certain other advantages are realized if the maleimides disclosed herein are used in conjunction with conventional nonmetallic thermal stabilizers to stabilize vinyl halide polymers against heat deterioration. Bis compounds of the N-alkyl maleimides disclosed herein, when used as thermal stabilizers for vinyl halide polymers, promote crosslinking without degrading the vinyl halide polymer.
