  • Cyclic imido-1,3,5-triazine crosslinking agents
    Patent number: 6013797
    Abstract: At least bis-imido 1,3,5-triazines and processes of preparing the same are disclosed. Also disclosed are prepolymers having at least bis-imido functionality and curable compositions comprising at least bis-imido 1,3,5-triazines or prepolymers thereof in combination with active hydrogen and/or epoxy functional materials. The at least bis-imido 1,3,5-triazines and prepolymers may be advantageously employed as crosslinking agents which crosslink by a ring opening reaction that eliminates the release of volatile organic compounds.
    Type: Grant
    Filed: March 20, 1998
    Date of Patent: January 11, 2000
    Assignee: Cytec Technology Corp.
    Inventors: Lon-Tang Wilson Lin, Robert G. Lees, William F. Jacobs, III, Subban Ramesh

  • Process for preparing isocyanate and isocyanate-based derivatives of certain amino-1,3,5-triazines by direct phosgenation
    Patent number: 5556971
    Abstract: A process is provided for preparing isocyanate and isocyanate-based 1,3,5-triazine derivatives by the direct phosgenation of (at least tris-unsubstituted amino)-1,3,5-triazines.
    Type: Grant
    Filed: May 6, 1994

  • N-hydroxysuccinimide-blocked isopropenyl-alpha, alpha-dimethylbenzyl isocyanate and self-cross linking copolymers thereof
    Patent number: 5252689
    Abstract: A novel, one component self-crosslinking resin and a process for its preparation are provided. The resin is the copolymer of:(I) N-hydroxysuccinimide-blocked meta-isopropenylalpha, alpha-dimethylbenzyl isocyanate;(II) a hydroxy group-containing ethylenically unsaturated monomer such as hydroxyethyl acrylate; and(III) optionally, an ethylenically unsaturated monomer free of hydroxy groups such as methylmethacrylate or butyl acrylate.The copolymers are useful as thermally stable fast curing one component resins for paint, and produce, upon heat curing, films and objects with good hardness and solvent resistance.
