<p>Curable mixtures are obtd. by mixing crystallised triglycidyl isocyanurate, with an epoxy oxygen content of at least 14%, with organic compounds which form polyadducts with epoxy compounds, in an amt. sufficient to cause hardening; the mixt. is heated until a degree of conversion of 15-30%, partic. 18-25%, is reached, and further conversion is stopped by cooling. The polyadduct formed after this pre-reaction is soluble in solvents such as acetone, dioxane, ethyl acetate and dimethyl sulphoxide. The polyadduct can be storred for several months without decrease in solubility. The polyadduct can be used in the production of laminates.</p> |
