An intensification and integration process of preparing thermal stable polylactide end-capped by phosphate ester

The phosphate ester capped polylactide was synthesized through employing calcium complex to catalyze the hydrophosphonylation reaction to generate alcoholic chain-transfer agent and immortal ring-opening polymerization in situ. The Tonset of the afforded PLLA was 338.22 °C, 57 °C higher than that of PLLA ended with benzyloxy group. This intensification and integration process is one hundred percent atom-economic efficiency.
