## Abstract Flow instability in a capillary extrusion is studied for a high molecular weight, plasticized poly(vinyl chloride) (PVC). The onset of melt fracture correlates with the long time relaxation ascribed to the generation and/or growth of PVC crystallites. An increase in the residence time i
## Abstract Measurements of solubility parameters of a series of chlorinated poly(vinyl chloride) (CPVC) samples were carried out. A maximum value of solubility parameter occurs at a chlorine content of 63β65% and is related to optimum packing.
In this work we investigate by means of dielectric relaxation spectroscopy how segmental motions occurring in poly(vinyl chloride) (PVC) are modified by blending of PVC with small amounts of two different homopolymers: crystalline poly(β-caprolactone) (PCL) and glassy syndiotactic poly(methylmethacr
