| abstract |
A PROCESS IS HEREIN DESCRIBED FOR CURING POLYMERS HAVING TERMINAL OR PENDANT ACID GROUPS. SAID PROCESS COMPRISES REACTING BY CONTACTING SAID POLYMERS WITH ONE OR MORE (1-AZIRIDINYL)ALKYL COMPOUND HAVING THE FORMULA ((TETRA(R0-)AZIRIDINO)-R1-Y-)N-R FOR EXAMPLE, TRIS(2-(1-AZIRIDINYL)ETYL) TRIMELLIATE IS A CURING AGENT FOR A CARBOXYL-TERMINATD POLYBUTADIENE. THE CURED AND UNCURED PRODUCTS ARE COMPOSITIONS WHICH ARE USEFUL IN MANY APPLICATIONS, E.G., IN THE PREPARATION OF ADHESIVES, CAULKING FORMULATIONS, AND PYROTECHNIC COMPOSITONS. |
