From melt to solution: Scaling relations for concentrated polystyrene solutions

摘要: The scaling relations established for the relaxation modulus of concentrated solutions polystyrene (PS) in oligomeric styrene [Wagner, Rheol. Acta 53, 765–777 (2014); Wagner, J Non-Newtonian Fluid Mech. (2015)] are applied to PS diethyl phthalate (DEP) investigated by Bhattacharjee et al. [Macromolecules 35, 10131–10148 (2002)] and Acharya [AIP Conf. Proc. 1027, 391–393 (2008)]. relies on difference ΔTg between glass-transition temperatures melt solutions. can be inferred from reported zero-shear viscosities, Baumgaertel, Schausberger, Winter (BSW) spectra obtained BSW spectrum reference with good accuracy. Predictions extended interchain pressure (EIP) model, which is based assumption that relative identical, compared steady-state elongational viscosity data o...
