Notes:
A factorial experiment shows that calcium stearate and paraffin wax significantly decrease the melt elastic modulus of rigid poly(vinyl chloride) formulations. It is also concluded the melt elastic modulus of PVC is not significantly affected by the presence of methyltin stabilizer, acrylic processing aids or polyethylene wax. The only significant interaction found was that between temperature and concentration of paraffin wax. A regression model was derived for shear storage modulus (G′) at a deformation frequency of 100 radians/sec. No significant correlation between G′ and critical shear rate for melt fracture was discernable.
