Flame retardant PLA from Phosphoramidates

In this research we have investigated the flame retardancy and thermal decomposition of polylactic acid (PLA) containing two different kinds of phosphoramidate flame retardants. Phosphoramidic acid, 1, 3-ethanediylbis-, tetramethyl ester (PAEDBTME) and Phosphoramidic acid, 1, 2-ethanediylbis-, tetraethyl ester ( PAEDBTEE) were synthesized as novel halogen free flame retardants and incorporated in the PLA polymer. Addition of these phosphoramidates to PLA increases its limiting oxygen index (LOI) and renders them self extinguishing in nature. Thermal decomposition studies were also carried out using thermo gravimetric analyzer (TGA) and pyrolysis combustion flow calorimeter (PCFC).
