Аннотация:For the first time, diacid derivative of limonene was obtained by thiol-ene reaction with mercaptoacetic acid and it was further used as a monomer for the synthesis of polyamides.Commercially available hexamethylenediamine and its siloxane analogue, bis(aminopropyl) tetramethyl disiloxane, were used as diamines monomers. It was shown that the introduction of a siloxane unit into the structure of a polyamide chain increasesthe molecular weight and thermal stability of the polymer (more than 300°C), and also affects its phase behavior at room temperature.
