Summary Low molar mass homopolymers, synthesized through free radical polymerization of acrylic acid under solvent control were reported. The polymers were characterized by FTIR, NMR, TGA, and GPC. The behavior as pour point improvers in biodiesel and blends biodiesel/diesel, were evaluated. By using 1000 ppm of the poly(tetradecyl acrylate) (A14) it was possible to decrease the pour point (PP) of neat biodiesel to −10°C, blend B5 to −39°C and blend B20 to −28°C, values below those reported in the literature. These results indicated that it would be possible to use higher amount of biodiesel in blends with diesel in regions where their use would not be feasible, mainly because of their poor flow properties.
