About this document

Synthesis of High Molar Mass PLA by Gustavo is a document available to read on EtoBox.

The document summarizes the synthesis of poly(L(+) lactic acid) (PLA) via a polycondensation method in solution. Specifically: 1) L(+) lactic acid was purified by distillation and used as the monomer. Stannous chloride and metallic tin were used as catalysts at 1.0 wt%. 2) Polycondensation was carried out in solutions of o-dichlorobenzene, p-xylene, o-chlorotoluene, and diphenyl ether for 10-20 hours. 3) The highest molar mass PLA was obtained in diphenyl ether under vacuum conditions. The resulting PL
