Notes:
The pure isomers of cyclic monomers were synthesized besides the linear polymers by cyclocondensation reactions of dodecanedioyl dichloride and the pure isomers of 4,4′-methylenedicyclohexylamine. The resulting cyclic amides were characterized by 1H NMR, IR and mass spectroscopy, as well as by HPLC and X-ray diffraction. The content of these cyclic amides in “Qiana”-Polyamide was determined by fractionated extraction and sublimation. Synthesis and properties of monomeric linear condensation product (dicarboxylic acid-type with blocked and free end groups) are also described.
