  • Acrylic modifiers for polycarbonamides
    Patent number: 4148846
    Abstract: An impact resistant nitrogenous polymer comprises a multiphase amine-reactive moiety-containing polymer grafted to a polycarbonamide containing recurring amide linkages as anintegral part of the polymer chain; the grafting, by reaction of an amine-reactive moiety of the polymer with an amine end group of the polycarbonamide. Preferably the amine-reactive moiety-containing polymer is a multiphase carboxylic acid-containing polymer comprising (A) a first elastomer phase that is preferably polymerized from monomers comprising: 50 to 99.
    Type: Grant
    Filed: December 5, 1977
    Date of Patent: April 10, 1979
    Assignee: Rohm and Haas Company
    Inventors: Frederick H. Owens, James S. Clovis
