Abstract
3-Pentadecylphenyl acrylate (PDPA) was synthesized from renewable sources (the cashew nut shell liquid), by using a novel organic chemical intermediate that can be used to copolymerize with vinyl monomers. A novel acrylic polyester hyper-dispersant was prepared by polymerization of methacrylic acid (MAA), butyl acrylate (BA), and PDPA. The acrylic polyester hyper-dispersants were used to disperse titanium dioxide in non-polar solvent system, and the dispersion performance was studied. The viscosity and particle size of suspensions were affected by monomer ratio and molecular weight; the results showed that the optimum monomer ratio and molecular weight were MAA:BA:PDPA = 1:10:1.2 (wt%) and 6000, respectively. The optimum amount weight of MAA of acrylic polyester should be around 10% (wt%).
