Synthesis and Characterization of Novel Nylons 2 14, 4 14, 6 14, 8 14, 10 14 and 12 14 |

| Abstract: | A series of novel even even nylons based on 1,12 dodecanedicarboxylic acid was synthesized by melt polycondensation. The structures and properties of the resulting products were characterized by means of infrared spectrometry (IR), 1H and 13 C nuclear magnetic resonance (NMR), differential scanning calorimetry (DSC), thermogravimetry analysis (TGA), dynamic mechanical analysis (DMA) and intrinsic viscosity. In addition, some basic mechanical properties of nylon 12 14 were measured. The properties of nylon 12 14 mediate between nylon 6 6 and polyethylene. Therefore long alkane segment nylons may fill the gap between nylon 6 6 and polyethylene in mechanical properties. |
