| Abstract: | The nylon 6-12 copolymer is prepared by anionic ring-opening polymerization. The results of TGA analysis show that the addition of laurolactam strengthens the thermal stability of nylon. The results of DSC analysis indicate that the addition of laurolactam increase the irregularity of nylon chain, decrease both the density of hydrogen bond and the crystallinity. The inftared spectra of NH group exhibit red shift phenomenon as well. |
