  • Maleimide resins
    Patent number: 9884942
    Abstract: A curable polymer composition comprising: (A) a thermoset maleimide resin precursor component; and further comprising one or both of: (B) an arylsulphone-containing maleimide component; and (C) a polyarylpolymer thermoplastic toughening agent component, wherein in the absence of component (B), said component (C) comprises one or more maleimide pendant and/or end groups, and thermoset resins and composites derived therefrom.
    Type: Grant
    Filed: December 20, 2012
    Date of Patent: February 6, 2018
    Assignee: CYTEC INDUSTRIES INC.
    Inventors: Steven Richard Ward, Paul Mark Cross, Robin Maskell
  • Multifunctional benzoxazines and composite materials incorporating the same
    Patent number: 9822219
    Abstract: A curable resin composition containing a blend of multifunctional benzoxazines, and composite materials derived therefrom. The benzoxazine blend contains the combination of (A) a difunctional benzoxazine component and (B) a multifunctional benzoxazine component with functionality of greater than 2. Cured matrix resins and cured composite materials containing such benzoxazine blend exhibit a significant retardation in the rate of organic solvent uptake as compared to the same cured matrix resins and composite materials without component (B).
