(Cl. 260-454) It is known that compounds which contain at least two epoxide groups per mol can be converted into in fusible artificial resins by means of cross-linking agents, such for example as polycarboxylic anhydrides, hardening taking place practically without the formation of volatile by-products and with only. very slight shrinkage. cal resistance such products are of considerable interest as cast products, lacquers or adhesives, especially for metals. As cross-linking agents there have been used only compounds in which the distance between. the groups capable of reacting with epoxide groups is small.
