Abstract

The space charge distribution of three samples of poly(vinyl chloride) of different isotactic content has been studied by the thermal step technique, with a view to investigating the influence of some defined microstructural features on that important behaviour. It has been observed that the space charge increases substantially as the content of the local tetrad configuration, mmr, at the end of isotactic sequences increases. A first tentative interpretation is given.

Isotactic, atactic, and syndiotactic poly(methyl methacrylate) (PMMA) were mixed with poly(vinyl phenol) (PVPh) separately in tetrahydrofuran to make three polymer blend systems. Differential scanning calorimetry (DSC) and Fourier transform infrared (FTIR) spectroscopy were used to study the miscibi
