Kinetics of reaction of C36 dimer acids with diethylenetriamine and triethylenetetramine for reactive polyamides

Abstract Kinetic studies were carried out on the reaction between C 36 dimer acids and diethylenetriamine (DETA) and triethylenetetramine (TETA) in melt phase. The reactions were performed at temperatures in the range of 145°C to 190°C and followed by determination of the acid and amine values of the intermittent products. The polyamidation reactions of C 36 dimer acids and DETA and TETA followed overall second‐order kinetics and had activation energies of 14.4 kcal/g mol and 12.3 kcal/g mol, respectively. © 1994 John Wiley & Sons, Inc.
