Abstract: NEW ADDUCTS, CONTAINING EPOXIDE GROUPS, OF POLYEPOXIDE COMPOUNDS AND POLYESTERS OF SUCCINIC ACID AND 1,4-BUTANEDIOL WHICH ARE SLIGHTLY BRANCHED, POSSESS TERMINAL CARBOXYL GROUPS AND HAVE AN AVERAGE MOLECULAR WEIGHT OF ABOUT 1200 TO 20,000, MANUFACTURED BY REACTION OF, FOR EXAMPLE, 11 MOLS OF SUCCINIC ANHYDRIDE WITH 10 MOLS OF 1,4-BUTANEDIOL, WITH 0,1 TO AT MOST 0.65 CARBOXYL GROUP EQUIVALENT OF THE ACID POLYESTER BEING EMPLOYED FOR THE (SO-CALLED) "ADVANCEMENT" PER 1 EQUIVALENT OF EPOXIDE GROUPS OF THE POLYEPOXIDE COMPOUND. BY CURING WITH CUSTOMARY CURING AGENTS FOR EPOXIDE RESINS, THE ADDUCTS CONTAINING EPOXIDE GROUPS CAN BE CONVERTED INTO ELASTOMERIC MOULED MATERIALS WHICH POSSESS A SIGNIFICANTLY GREATER HARDNESS AND TOUGHNESS AND A SURPISINGLY HIGH CRYSTALLIZATION TRANSITION POINT OF 70-100*C.

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.
