The Synthesis and Solubility of a Wholly Aromatic Polyamide Containing para-and meta-Substituted Phenylene Rings
A series of wholly aromatic polyamides (aramid) containing para-and meta-substituted phenylene rings was eopolymerized via phosphorylation method with different ratio of 4-aminobenzoic acid and 3-aminobenzoic acid.The inherent viscosities (ηinh) of products were 0.52-0.99 dL/g.The chain structure of the polymers was characterized by Fourier transform infrared spectroscopy (FT-IR) and Raman spectrum.The differential scanning calorimetry (DSC) was also performed to investigate the chain transformation behavior of aramid.With increasing the content of meta-substituted phenylene rings in macromolecular chain, the solubility of the polymers was improved obviously without appreciable loss for their original thermal property.
