| Abstract | ||||
| Non-reactive polyamides were prepared by reacting dimer fatty acids and, two different diamines such as ethylenediamine and isophornedimine, to obtain a product. The dimer fatty acid used was of dimer/trimer/ Monomer mixtures, ≥80/≤18/≤5. all the polyamides prepared, the number average molecular weight (Mn) ranged from 2479-2803, weight average molecular weight (Mwt) from 6761-10220, Z weight average molecular weight(Mz) from 13532-26876, and the most fundamental characteristic of a polymer its molecular weight distribution(PDI) degree of polymerization ranged from 2.727-3.713, and the glass transition was 76.46-98.9°C. Evaluation gloss and color strength polyamides in ink on films (paper, polyethylene milk, and polyvinylchloride). Most of these polyamides have properties comparable to the commercially available polyamides used in flexographic inks. | ||||
