The existence of entirely biobased AA–BB polyamides is very limited because of the low availability of biosourced diamines. In this work, saturated and unsaturated diamines, with dangling hexyl chain, were successfully synthesized from methyl ricinoleate. These new monomers were reacted with several diacids to prepare novel partially to totally biobased AA–BB polyamides. Linear polyamide analogues were also prepared from commercial monomers. The physico‐chemical properties of the obtained polymers were assessed by DSC and TGA analysis. An auto‐plasticizing effect owing to the dangling chains was evidenced. The new branched monomers and polymers are expected to be used when modification of the properties of existing polyamides are required. Practical applications: The new branched monomers and polymers are expected to be used as green and renewable plasticizers for modification of the properties of existing polyamides. Furthermore, the presence of the carbon–carbon double bonds in the main chains would be beneficial to perform polyamide chemical modifications at the molten state or to achieve cross‐linking reactions suitable for coating applications.
