Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
173 words
A PERMANENTLY FUSIBLE, THERMOPLASTIC ADHESIVE COMPRISING A RESINOUS POLYAMIDE REACTION PRODUCT OF A POLYMERIC POLYENE FAT ACID AND AN ALKYLENE POLYAMINE PROSSESSING AT LEAST TWO PRIMARY AMINO GROUPS, AND A MINOR PROPORTION OF A RESINOUS POLYEPOXIDE REACTED WITH SAID POLYAMIDE, SAID POLYAMIDE HAVING AN AMINE VALUE IN EXCESS OF 1 MG. OF -NH2 PER GRAM OF POLYAMIDE, AND SAID RESINOUS POLYPEOXIDE BEING A RESINOUS GLYCIDYL POLYETHER OF A MEMBER OF THE GROUP CONSISTING OF POLYHYDRIC PHENOLS, POLYHYDRIC ALCOHOLS AND MIXTURES OF THESE, SAID RESINOUS POLYEPOXIDE BEING PRESENT IN AMOUNTS FROM 1/4% BY WEIGHT BASED ON THE WEIGHT OF SAID POLYAMIDE TO NOT MORE THAN ABOUT 90% OF THAT QUANTITY WHICH WILL FORM IN A MIXTURE CONSISTING OF THE POLYAMIDE AND POLYEPOXIDE HEATED FOR ONE-HALF HOUR AT 150*C. A GEL STRUCTURE IN WHICH A 3/10" STEEL BALL WILL JUST BEGIN TO FALL ERRATICALLY THROUGH A BODY OF THE RESIN IN A GLASS TUBE 1" IN DIAMETER AT A TEMPERATURE OF 150*C., SAID POLYEPOXIDE SERVING TO INCREASE THE DIMENSIONAL STABILITY AND STRENGTH OF THE COMPOSITION.
