The properties and thermal treatment effects on the microstructure and stress-strain behaviors of two transparent polyamides, poly(4,4′-aminocyclohexyl methylene dodecanedicarboxylamide (PAPACM12) and poly(3,3′-dimethyl-4,4′-aminocyclohexyl methylene dodecanedicarboxylamide (PAMACM12), were studied in this work. Differences in microstructure and the corresponding properties between the two polymers with similar repeating units were found out via comparative analyses. PAPACM12 behaved as a microcrystalline polymer with a distinct glass transition temperature of 135.6 °C and a melting point at 244.6 °C. By contrast, PAMACM12 showed a higher glass transition temperature of 160 °C, as the elimination of thermal history reduced a lot its crystallinity. Besides, cold crystallization was observed for PAPACM12 during the heating process, which gave rise to an exothermic peak on the DSC curve at 174 °C. Comparing the Fourier transform infrared spectroscopy (FTIR) spectra of two polyamides, the band of 961 cm⁻¹ as a crystalline indicator was found present for PAPACM12 but absent for PAMACM12. This observation was consistent with the DSC results obtained above. Further, thermal treatment effects on the aggregate structure and tensile properties were investigated. Experimental results showed that quenching treatment could reduce the yield strength and elongation at break for both samples. Besides, the cold crystallization of PAPACM12 after annealing let two diffraction peaks occur on the integrated pattern of wide-angle X-ray diffraction (WAXD), which corresponded to the d-spacings of 0.50 and 0.45 nm, respectively. These two values approximated to the ones for (100) and (010/110) lattices in the AABB-type polyamides. Moreover, the tensile strength of PAPACM12 increased while the fracture strength decreased after annealing, for cold crystallization process conduced to an improved microcrystalline formation. Differently, both tensile strength and fracture strength of PAMACM12 were decreased by annealing, but its optical transparency was barely affected.
