Divergent Process for C 10 , C 11 and C 12 ω-Amino Acid and α,ω-Dicarboxylic Acid Monomers of Polyamides from Castor Oil as a Renewable Resource

E-mail: ygkim@snu.ac.krReceived February 25, 2012, Accepted March 2, 2012Polyamides have great potentials for diverse applications and the present production of their monomers mostlyrelies on resources from fossil fuel. Starting from undecylenic acid, a natural resource, we have developed bothdivergent and efficient processes for C
