Production of new types of effective and green softeners for polyvinylchloride (PVC) is one of the important concerns in chemical industry. The paper reports results of investigations on obtaining symmetric esters of a series of fatty acids and triethylene glycol (TEG) and their use as effective PVC plasticizing agents. The esterification process was conducted in the presence of nano-grade titanium dioxide Degussa P-25 and specified by environmentally sound technology. Good compatibility and low volatility of the bio-based type esters in PVC formulations were shown and higher physico-mechanical features of the PVC composites were established. The esters may be recommended as effective and environmentally friendly PVC softeners to replace commonly used phthalates.
