COMPOSITION OF EPOXIDE RESINS, POLYCARBOXYLIC ACID ANHYDRIDES AND POLYESTER-DICARBOXYLIC ACIDS |
摘要 |
<p>Curable epoxide resin mixtures based on long-chain adducts containing epoxide groups, which are obtained by reaction of certain long-chain aliphatic polyesters with an excess of diepoxide compounds, polycarboxylic acid anhydrides and linear polyester-dicarboxylic acids containing carbocyclic or heterocyclic rings, which mixtures contain, per 1 equivalent of epoxide groups, 0.2-0.8 mol of polycarboxylic acid anhydride and 0.8-0.2 equivalent of carboxyl groups of the polyester-dicarboxylic acid. Curing of these epoxide resin mixtures gives flexible moulding materials which are distinguished by high tear propagation resistance.</p> |
