Some thermodynamic, kinetic, and mechanistic aspects of the ring-opening polymerization of 1,4-dioxan-2-one initiated by Al(OiPr)3 in bulk
Abstract
<p>1,4-Dioxan-2-one (PDX) was polymerized in bulk by means of aluminum triisopropoxide (Al(O<sup>i</sup>Pr)<sub>3</sub>) as initiator. Thermodynamic parameters and ceiling temperature were determined from the temperature dependence of the monomer conversion over the range from 60 to 150 °C. It highlights that the thermodynamic equilibrium monomer conversion depends strongly on the final amorphous or crystalline state of poly(1,4-dioxan-2-one) (PPDX), at least below its melting temperature. The kinetics of the PDX polymerization for various monomer-to-Al(O<sup>i</sup>Pr)<sub>3</sub> ratios at 80 °C is typically first order in both monomer and initiator and characterized by an absolute rate constant of 0.08 L mol<sup>-1</sup> s<sup>-1</sup>. Molecular weight increases regularly with monomer conversion and initial monomer-to-Al ratio, while polydispersity is kept quite narrow all along the polymerization (M<sub>w</sub>/M<sub>n</sub> < 1.3). Mechanistic investigations proved that Al(O<sup>i</sup>Pr)<sub>3</sub> is an efficient initiator for promoting the ring-opening polymerization that proceeds through a coordination-insertion mechanism with a selective rupture of the acyl-oxygen bond of the monomer.</p>
