  • Polyepoxide-polyoxyalkylene monoamine(s) product with hardener
    Patent number: 5585446
    Abstract: An epoxy resin composition is disclosed that contains compounds that contain at least two 1,2-epoxide groups. The epoxide group-containing compounds are reaction products of compounds (A1) that contain at least two 1,2-epoxide groups per molecule, compounds (A2) that are polyoxyalkylenemonoamines that have a molecular weight of from 130 to 900 and, if desired, polyoxyalkylenemonoamines (A3) that have a molecular weight of from 900 to 5000 and/or polycarboxylic acids (A4). The resin composition additionally contains at least one hardener (B) and, if desired, customary additives (C).
    Type: Grant
    Filed: December 12, 1994
    Date of Patent: December 17, 1996
    Assignee: Hoechst Aktiengesellschaft
    Inventors: Manfred Marten, Bernhard Wehner

  • Epoxy resin/polyoxyalkylenemonoamine product with hardener
    Patent number: 5459208
    Abstract: An elastically-cured epoxy resin composition is disclosed that contains compounds that contain at least two 1,2-epoxide groups. The epoxide group-containing compounds are reaction products of compounds (A1) that contain at least two 1,2-epoxide groups per molecule, polyoxyalkylenemonoamines (A2) that have a molecular weight (number average) greater than 900 g/mol, and optionally polycarboxylic acids (A3). The polyoxyalkylenemonoamines (A2) are polyoxypropylenemonoamines which preferably contain a mole fraction of up to 20% of oxyethylene units based on the total amount of oxypropylene and oxyethylene units. The resin composition additionally contains at least one hardener (B) and, if desired, customary additives (C).
