Abstract: The aromatic polyamides were prepared by polyeondensation of terephthaloyl or isophthaloyl dichloride with 2,4,6-trimethyl-1,3-phenylenediamine. The influences of the monomer concentration and polymerization conditions on the degree of polymerization were studied. The polymers obtained have a greater solubility than common polyamides with less methyl groups on the benzene ring.

Key words: trimethyl phenylenediamine, terephthaloyl dichloride, isophthaloyl dichloride, polyamide, synthesis
