STUDY OF LIQUID-CRYSTALLINE BEHAVIOUR OF ALIPHATIC-AROMATIC POLYAMIDE BY DSC ANALYSIS
Keywords:
Dimer acid, aliphatic-aromatic polyamide, p-phenylene diamine, differential scanning calorimetry.Abstract
Aliphatic-aromatic polyamide of castor oil based dimer acid (DA) with p-phenylene diamine (PPD) was characterized by differential scanning calorimetry. This polyamide exhibited interesting liquid-crystalline behaviour which was quite unexpected looking at the structure of dimer acid moiety.
