Abstract

The invention relates to a process for preparing a polyester of a glycerol and a carboxylic diacid, comprising (a) bringing the monomers comprising at least the glycerol and a carboxylic diacid into contact in the presence of water, at a temperature of less than 100°C in an inert atmosphere, with a glycerol/carboxylic diacid molar ratio ranging from 0.5/1 to 10/1; (b) esterification in an inert atmosphere at a temperature above 110° C; (c) vacuumizing the reaction medium at a pressure of less than 100 mbara and at a temperature above 110° C; and (d) maintaining the vacuum and a temperature higher than 110°C in order to perform a polycondensation process, which method comprises the introduction of a polycondensation catalyst at the end of the esterification of step (b), before the vacuumizing of step (c) or after the vacuumizing of step (c), in an amount of less than or equal to 5000 ppm relative to the total mass of monomers, said catalyst being a tin-based food-grade catalyst selected from organotin compounds having a carboxyl function (-C(O)OH), organotin compounds having a (-Sn(O)OH) function, and monobutyltin tris(2-ethylhexanoate). Such a process makes it possible in particular to synthesize a glycerol polyester having a residual monomer content of less than 5% by weight of the weight of the polymer, a high number-average molar mass Mn of greater than 2500 g/mol, a dispersity (Mw/Mn) of less than or equal to 10, and less than 15 mol % of units (1,2,3-triacylglyceride) relative to all the units of the polymer.
