The invention relates to polyesters containing at least one partly acylated polyhydroxylated compound belonging the group consisting of glycerol polycarbonates, specific polyglycerols, [(a-hydroxymethyl) oxyethylene/(a-hydroxymethyl)ethylene carbonate] copolymers, [a -hydroxymethyl) oxyethylene/(a-hydroxymethyl)ethylene carbonate] copolymers, and [a -alkyl) oxyethylene/(a-hydroxyalkyl) oxyethylene] copolymers. The invention also relates to methods for acylating, at least partly, the polyhydroxylated compounds. The polyesters of this invention are applicable to the technical fields relating to engine and industrial lubricants, greases, hydraulic fluids, metal deformation and processing lubricants, stripping and mold dressing products, oil prospecting, mines, tunnel borers, cosmetics, detergency, inks, textile coatings and papers, to the field of food products, to the protection of wood as synthesis intermediates.
