Abstract:he aromatic-aliphahc copolyamide based on terephthalyl chloride (TPC), p-phenylenediamine (PPD) and 1, 6-hexanediandne (HDA) was synthesis by low temperature solution copolycondensahon in abide-salt solvent system. The effeCts of the add accepters (AA) and each components of the amide-salt solvent system on the sequence structure, random degree (B) and number average sequence length (Ln), were studied. In order to obtain the aromatic-aliphahc copolyandde with higher B and less Ln, the PKa of AA usually has to be similar to the PKa of diawhnes used as monomers and the g and DN of solventS used should be higher and the amount of the salt used must be reasonable in polycondensahon system.
Keywords:Aromatic-aliphatic copolyamide   Sequence structure   Acid accepter   Amidesalt solvent system
