Abstract: Non-porous materials are bounded by introducing between the surfaces to be bonded monomeric polyfunctional aromatic cyanic acid esters resp. their prepolymers obtained by heat treatment of the monomeric compounds, fixing the surfaces to be bonded in the required position under intimate contact and heating the bond for a sufficient period of time up to 250* C.

Abstract: AN ADHESIVE COMPOSITION ESPECIALLY FOR RUBBER, LEATHER, TEXTILES OR PLASTICS AND MOST ESPECIALLY FOR SOFT POLYVINYL CHLORIDE. THE COMPOSITION IS THE REACTION PRODUCT OF A DIISOCYANATE WITH TWO POLYESTERS, ONE OF WHICH IS A BENZENE DICARBOXYLIC ACID ALKYLENE POLYESTER WITH A MOLECULAR WEIGHT UP TO 600, PREFERABLY UP TO 300, WHILE THE OTHER POLYESTER IS EITHER AN ALKANE DIOL POLYCARBONATE OR AN ALKANE DIOL DICARBOXYLIC ACID POLYESTER WITH A MOLECULAR WEIGHT BETWEEN 600 AND 3000, PREFERABLY BETWEEN 1500 AND 2500. THE PREFERRED FIRST POLYESTER IS A POLYESTER MADE FROM PHTHALIC ACID AND ETHYLENE GLYCOL. THE SECOND POLYESTER IS PREFERABLY AN ADIPIC ACID/BUTANE DIOL POLYESTER OR AN ADIPIC ACID/HEXANE DIOL POLYESTER. IF POLYCARBONATE IS EMPLOYED HEXANE-1,6-POLYCARBONATE IS PREFERRED. TOLUYLENE DILSOCYANATE IS THE TYPICAL ISOCYANATE.
