Kinetic Parameters of Ring-Opening Polymerization of Poly (Lactic Acid) using Stannous Octoate With / Without Triphenylphosphine as an Initiator

Paramjit Kaur ^[3]

Abstract: The modeling of ring opening polymerization of L- lactide to poly (lactic acid) (PLA) has been carried out. Using a simple numerical technique, the individual rate constants are evaluated theoretically and are compared with the available experimental data. On comparing the rate constants for PLA polymerization synthesized using 2-ethylhexanoic acid tin(II) salt (stannous octoate) with and without triphenylphosphine (TPP), several interesting results are obtained. An attempt has also been made to quantify the kinetics of the polymerization when TPP is added to stannous octoate.
