Kinetic studies were carried out on the reaction between 2-Methyl 1,5 diaminopentane and dimeric fatty acids in melt phase. The reaction was performed at 113, 130, 140, 155, and 164 ºC and followed by determining the acid value of the product .The polyamidation reaction was found to be of overall second order with an activation energy of 45.48 k cal⁄g mol up to (52, 57, 79, 80, 86)% conversion at (113, 130, 140, 155, 164) ºC and overall third order with an activation energy of 43.73 k cal⁄g mol above (52, 57, 79, 80, 86)% conversion at (113, 130, 140, 155, 164) ºC.
