Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
46 words
A COMPOSITION WHICH UPON HARDENING BECOMES A HEAT RESISTANT SYNTHETIC RESIN COMPRISING A HARDENABLE GLYCIDE ESTER OF A,A''-(9,10-DIHYDRO-ANTHYLENE-(9,10))-SUCCINE ACID CONTAINING MORE THAN ONE POXIDE GROUP IN THE MOLECULE AND FROM ABOUT 10% TO ABOUT 70% OF THE WEIGHT OF THE COMPOSITION OF A HIGH-TEMPERATURE POLYFUNCTIONAL HARDENER.
Claim 2
Dependent Claim
46 words
A COMPOSITION WHICH UPON HARDENING BECOMES A HEAT RESISTANT SYNTHETIC RESIN COMPRISING A HARDENABLE GLYCIDE ESTER OF A,A''-(9,10-DIHYDRO-ANTHYLENE-(9,10))-SUCCINE ACID CONTAINING MORE THAN ONE POXIDE GROUP IN THE MOLECULE AND FROM ABOUT 10% TO ABOUT 70% OF THE WEIGHT OF THE COMPOSITION OF A HIGH-TEMPERATURE POLYFUNCTIONAL HARDENER.
Claim 3
Dependent Claim
72 words
THE PROCESS OF PRODUCING HEAT RESISTANT HARDENER EPOXY RESINS WHICH COMPRISES THE STEPS OF MIXING TOGETHER A HARDENABLE GLYCIDE ESTER OF A,A''-(9,10-DIHYDRO-ANTHRYLENE-(9,10))-SUCCINIC ACID CONTAINING MORE THAN ONE EXPOXIDE GROUP IN THE MOLECULE AND FROM ABOUT 10% TO ABOUT 70% OF THE WEIGHT OF THE COMPOSITION OF A HIGH TEMPERATURE POLYFUNCTIONAL HARDENER, AND HEATING THE COMPOSITION TO A TEMPERATURE BETWEENABOUT 80*C. AND 250*C. FOR A TIME SUFFICIENT TO PRODUCE A HARDENED EPOXY RESIN.
