Production of polyesteramides from aziridine salts

Abstract

Abstract WHERE R1, R4, R5 AND R6 HAVE THE MEANINGS GIVEN ABOVE. -OOC-R1-CO-R4-CO-R1-COO-R6-OOC-R5-COO-R6- WHERE R4 HAS THE MEANING GIVEN ABOVE. THE ABOVE DIACID MAY THEN BE REACTED WITH THE POLYCARBOXYLIC ACID AND THE POLYHYDRIC ALCOHOL TO FORM A POLYESTERAMIDE REPRESENTED BY THE STRUCTURAL FORMULA HOOC-R1-CO-R4-CO-R1-COOH WHEREIN R1 HAS THE MEANING GIVEN ABOVE, TO YIELD A DIACID REPRESENTED BY THE STRUCTURAL FORMULA HOOC-R1-COOH WHEREIN R1 HAS THE MEANING GIVEN ABOVE; R4 REPRESENTS A DIVALENT RADICAL SUCH AS AMINOALKYLENEOXY OR OXYALKYLENEOMINO; R5 REPRESENTS A DIVALENT RADICAL SUCH AS ALPHA-BETA ETHYLENICALLY UNSATURATED ALKYLIDENE; AND R6 REPRESENTS A DIVALENT RADICAL SUCH AS ALKYLENE OR ALKYLIDENE. THE ABOVE AZIRIDINE SALT MAY ALSO BE REACTED WITH AN ACID REPRESENTED BY THE STRUCTURAL FORMULA -OOC-R1-CO-R4-CO-R5-COO-R6- WHEREIN R1 REPRESENTS A DIVALENT RADICAL SUCH AS ALKYLENE, ARYLENE, OR ARALKYLENE, WHEREIN ONE OR ALL OF THE HYDROGEN ATOMS THEREOF CAN BE SUBSTITUTED WITH F, CL, BR, LOWER ALKYL AND/OR LOWER ALKOXY; AND WHERE R2 AND R3 REPRESENT MONOVALENT RADICALS SUCH AS HYDROGEN, ALKYL, OR ARYL; IS REACTED WITH A POLYCAROBOXYLIC ACID, SUCH AS MALEIC OR DIMER ACID, AND WITH A POLYHYDRIC ALCOHOL, SUCH AS CASTOR OIL OR 1,6-HEXANE DIOL, TO FORM A POLYESTERAMIDE REPRESENTED BY THE STRUCTURAL FORMULA: HOOC-R1-COO(-) (+)H2N<(-CH2-C(-R2)(-R3)-) AN AZIRIDINE SALT REPRESENTED BY THE STRUCTURAL FORMULA:
