Effect of nanocalcium carbonate on the impact strength and accelerated weatherability of rigid poly(vinyl chloride)/acrylic impact modifier

Poly(vinyl chloride) (PVC) composites filled with nano‐ and micro‐CaCO3 particles were prepared via a melt blending method. Transmission electron microscopy images revealed better dispersion of nano‐CaCO3 than micro‐CaCO3 in the PVC matrix. With more than 5 phr (parts per 100 parts of resin) of nano...

Zusammenfassung:Poly(vinyl chloride) (PVC) composites filled with nano‐ and micro‐CaCO3 particles were prepared via a melt blending method. Transmission electron microscopy images revealed better dispersion of nano‐CaCO3 than micro‐CaCO3 in the PVC matrix. With more than 5 phr (parts per 100 parts of resin) of nano‐CaCO3 content, both impact strength and heat stability were improved. Accelerated weathering tests were performed to investigate UV stability. The impact strength and white index obtained upon weathering exposure of PVC/(80 μm CaCO3) nanocomposites showed a significant improvement upon incorporating nano‐CaCO3. J. VINYL ADDIT.
