    Abstract: HEAT-CURABLE EPOXIDE RESIN MIXTUREES OF (1) A CYCLOALIPHATIC POLYGLYCIDYL COMPOUND WHICH POSSESSES AT LEAST ONE ALICYCLIC FIVE-MEMBERED OR SIX-MEMBERED RING, (2) A POLYCARBOXYLIC ACID ANHYDRIDE (0.2-1.1 ANHYDRIDE GROUPS PER 1 EQUIVALENT OF EPOXIDE GROUPS) AND (3) A POLYESTER CONTAINING TERMINAL CARBOXYL GROUPS AND/OR HYDROXYL GROUPS, WHICH IS OBTAINED BY ESTERIFICATION OF ALIPHATIC-CYCLOALIPHATIC HIGHER DICARBOXYLIC ACIDS (MANUFACTURED BY DIMERIZATION OF UNSATURATED MONOMERIC FATTY ACID WITH 14-24 CARBON ATOMS IN THE MOLECULE, PREFERABLY 16-18, AND OPTIONALLY SUBSEQUENT HYDROGENATION OF SUCH A DIMERIC FATTY ACID) WITH ALIPHATIC DIOLS (0.02-0.4 MOL OF POLYESTER PER 1 EQUIVALENT OF EPOXIDE GROUPS). THE CURING OF THE MIXTURE YIELDS FLEXIBLE, IMPACT-RESISTANT MOULDINGS THE PHYSICAL PROPERTIES OF WHICH SHOW LITTLE TEMPERATURE-DEPENDENCE, AND WHICH POSSESS HIGH FLEXIBILITY AT LOW TEMPERATURES.

    Abstract: 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.
