Kinetics of reaction of C36dimer acids with diethylenetriamine and triethylenetetramine for reactive polyamides

摘要

AbstractKinetic studies were carried out on the reaction between C36dimer 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 C36dimer 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 WileySons,
