Synthesis and elaboration of modified comb type (maleic anhydride-α-tetradecene) copolymers for cold flow improvers of biodiesel

This study assessed the effect of different proportions of alkyl/ carboxyl group ratio and alkyl side chain length on cold flow improvement on wax crystallization and biodiesel flow ability by pour point testing and dynamic viscosity measurements. Moreover, the palm oil biodiesel (PB), the waste oil biodiesel (WB), and the animal fat biodiesel (AFB) were used to test the pour point reducing ability of the synthesized CFIs.
