  • Pavement marking composition
    Patent number: 6521718
    Abstract: A pavement marking composition comprises (a) a polyfunctional ethylenically unsaturated polymer selected from the group consisting of polyfunctional ethylenically unsaturated polyurethanes, polyureas, polythiocarbamates, polythiocarbamateurethanes, polythiocarbamateureas, and polyurethaneureas comprising at least one chain extender-derived segment and at least one polycarbonate, polyether, or polyester segment; and (b) at least one ethylenically unsaturated monomer. The composition can be easily applied, cures in a reasonable amount of time at any of a wide range of commonly-encountered temperatures, and provides pavement markings that exhibit both improved cold impact resistance and improved wear resistance.
    Type: Grant
    Filed: June 13, 2001
    Date of Patent: February 18, 2003
    Assignee: 3M Innovative Properties Company
    Inventors: Siegfried Rainer Goeb, Anja Christina Rohmann

  • Polyfunctional polymer
    Patent number: 6107436
    Abstract: Polyfunctional ethylenically unsaturated polyureas, polythiocarbamateureas, and polyurethaneureas comprise (a) at least one segment derived from an aspartic ester polyamine; and (b) at least one polycarbonate, polyether, or polyester segment. The polyfunctional polymers are useful in preparing curable coatings, films, and articles.
