摘要: Blends containing PVC and aramid (Ar) matrices were probed for their miscibility. In this respect, Ar chains synthesized by aromatic diamine diacid chloride in amide solvent. The thus was characterized through Fourier transform infrared (FTIR) spectroscopy molecular weight determination. Blend system Ar/PVC investigated over a range of ratios. Their mechanical profiles terms maximum stress, strain, toughness, initial moduli have been explored. Thermal properties morphology the blends estimated using thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), electron microscopy (SEM). A good correlation observed between thermal, mechanical, morphological blends. presence hydrogen bonding among polymers evaluated FTIR spectroscopy, which is believed to be responsible blend Optimal thermal depicted 40-wt% matrix.
