Compatibility of PMMA/PVC Binary Blends

The morphological structures and properties of the PMMA/PVC binary blends were studied by DSC, FTIR, SEM and mechanical test. The special interaction forces between PMMA and PVC at the specified blend composes were found, which shows the high possibility to form a kind of good polymer alloy, the results coincide with predictions in terms of the Fox equation and the modified Flory's equation of state theory by Hamada et al.
