KINETICS OF REACTION OF C-36 DIMER ACIDS WITH DIETHYLENETRIAMINE AND TRIETHYLENETETRAMINE FOR REACTIVE POLYAMIDES

Kinetic studies were carried out on the reaction between C36 dimer aci ds and diethylene-triamine (DETA) and triethylenetetramine (TETA) in m elt phase. The reactions were performed at temperatures in the range o f 145-degrees to 190-degrees-C and followed by determination of the ac id and amine values of the intermittent products. The polyamidation re actions of C36 dimer acids and DETA and TETA followed overall second-o rder kinetics and had activation energies of 14.4 kcal/g mol and 12.3 kcal/g mol, respectively.
