The use of renewable resources in supplementing and/or replacing traditional petrochemical products, through green chemistry, is becoming the focus of research. The utilization of oils can play a primitive role towards sustainable development due to their large scale availability, built-in-functionality, biodegradability and no net CO2 production. Further, the expansion of crude glycerol applications is the foremost importance for the growing biodiesel industry, where methods with low energy consumption, shorter times and high yield are desired. Here we report the rapid conversion of glycerol and fatty methyl esters to monomers and biopolymers thereoff. The optimal predicted parameters were determined by the higher monomers yield at then polymers were synthesized using solution and bulk polymerizations. The polymers were characterized in details for their structural, thermal, mechanical and viscoelastic properties. The ability for complete conversion under solvent free conditions and synthesis of different biopolymers is undoubtedly an attractive concept from both an academic and an industrial point of view
