The new compound tri-( Beta -methylglycidyl)-isocyanurate is manufactured by a reaction, which is in itself known, of cyanuric acid with Beta -methylepichlorhydrin in the presence of tertiary amines or quaternary ammonium salts, and subsequent dehydrohalogenation with alkali. In comparison with the known tri-(glycidyl)-isocyanurate, tri-( Beta -methyglycidyl)isocyanurate can be more easily processed, on the one hand because of the lower melting point and on the other hand because of the lesser reactivity. Apart from compression moulding compositions, the material is therefore also excellently suited to being used as a casting resin. Suitable curing agents are above all polysebacic anhydride, and also aliphatic polyamines. Using the latter, it is surprisingly possible to manufacture a stable B-stage which is for example suitable for the manufacture of compression moulding compositions. |
