The objective of this project was to investigate different types of organic compounds applied onto rutile titanium dioxide (TiO2) and to determine how each of them affects the processing and properties of rigid poly(vinyl chloride) (PVC). The first part of the research was an initial study on three types of organic-coated pigments. Sample 1 consisted of 0.2 weight % trimethylol propane (TMP) and 0.5 weight % poly(dimethyl siloxane) (PDMS), whereas samples 2 and 3 were single coated with 0.3 weight % TMP and O.B weight % n-octyl-phosphonic acid (OPA), respectively. The dispersion behaviour of coated pigments in liquid paraffin and water indicated that sample 1 was hydrophobic, sample 2 was hydrophilic and sample 3 was amphipathic.
