Abstract Vegetable oil based biodegradable polymeric additives have attracted much attention keeping in view the increasing environmental concern. In the present context homopolymer of behenyl acrylate, and its different copolymers with varied percentages of Citral have been synthesised via free radical polymerisation. All the prepared polymers were characterised by FT–IR and NMR spectroscopy and their molecular weights were measured by GPC. Their performances as pour point depressant (PPD) and viscosity index improver (VII) in lube oil have been evaluated. Thermo Gravimetric Analysis (TGA) of these polymers accounted for their thermal stability as a polymeric additive. Also eco-friendly nature of the Citral based polymers was established via biodegradability test. The results have successfully sought for the establishment of a potential candidate towards application of greener additives in automotive industry.
