Abstract

In this study, Poly(styrene-co-chloromethyl styrene) [Poly(St-co-CMS)] was prepared and used in the modification of triglyceride oils. The obtained modified triglyceride product was examined in view of oil-based binder. Nitroxide-mediated radical polymerization (NMRP) technique was applied for Poly(St-co-CMS) synthesis. Chloro groups on the Poly(St-co-CMS) backbone were reacted with 2-amino-1-butanol (2-AB) in order to obtain a polymer with hydroxyl ended side branches, [Poly(St-OH)], which were further combined with partial glycerides (PGs) through the reaction with toluene diisocyanate (TDI). The resulting product can also be considered as a polystyrene-modified urethane oil [Poly(St-OH)-SUO]. The structures of both intermediates, [Poly(St-co-CMS), Poly(St-OH)], and final products [Poly(St-OH)-SUO] were verified by using FTIR and H-1-NMR analyses. Additionally, thermal properties of the samples were determined. The film properties of Poly(St-OH)-SUO samples prepared with different polymer/oil ratios and classic urethane oil were examined. Poly(St-OH)-SUO-40 sample exhibited the best film properties among the others. In the end, the obtained results showed that Poly(St-OH)-SUO-40 could be utilized as an oil-based binder.
