Orientation of amorphous, miscible poly(vinyl phenol) (PVPh)-poly(ethylene terephthalate) (PET) blends is studied using experimental and modelling techniques. Up to 50wt% PVPh, the blends are semi-crystalline and were therefore not studied. At 60wt% PVPh, no crystallisation was observed using either differential scanning calorimetry or X-ray diffraction. For the 60wt% PVPh blend, FTIR dichroism determination...
Molecular simulations of poly(vinyl phenol)/poly(vinyl methyl ether) (PVPh/PVME) blends were performed and their degree of miscibility evaluated as a preliminary step before orientation simulations. A minimum of three periodic boundary condition amorphous models was constructed and analysed in terms of solubility parameter, X-ray pattern, pair correlation function, hydrogen bond fraction and backbone...
Orientation of poly(vinyl phenol) (PVPh)–poly(vinyl methyl ether) (PVME) amorphous miscible blends has been studied using FTIR spectroscopy. Blends of 33, 42, 53 and 66% (mol/mol) in PVPh were uniaxially stretched at 0.1s−1 and Tg+15. Both polymers showed similar orientation values in the blend. Whereas, at high PVPh concentration, the orientation function 〈P2〉 is linear with deformation, at intermediate...
