Preparation and prediction of physical properties of cellulose acetate and polyamide polymer blend

摘要

In this paper the physical properties of the polymer blend of lab synthesized Polyamide (PA) and commercial Cellulose Acetate (CA) was focused. The molecular interactions of CA/PA were investigated thoroughly by means of solubility, viscosity, specific gravity and diffusivity study with different concentrations of the CA/PA combinations and the blend of CA/PA was characterized by optical microscope and differential scanning calorimetry (DSC). Dimethyl formamide (DMF) was selected as solvent for the CA/PA polymer blend at 28 degrees C. The diffusivity result for the polymer blend of CA/PA was suggested slight decrease in diffusivity coefficient with 1:1 blend ratio of CA/PA polymer. (C) 2017 Elsevier Ltd. All rights reserved.
