| 摘要 |
Compositions of matter comprising a liquid thiol terminated polysulfide polymer, a liquid epoxy resin and a liquid amine terminated polymer containing from about 1.7 to about 4 amine groups per molecule of the general formula <IMAGE> wherein Y is a univalent radical derived by removal of an amine hydrogen from an aliphatic, alicyclic, heterocyclic or aromatic amine containing from 2 to about 20 carbon atoms and at least 2 amino groups and B is a polymeric backbone comprising carbon-carbon linkages are disclosed. Insulated window units fabricated therefrom possess superior mechanical and dewpoint retention properties.
