The invention concerns an organic composition comprising glycerol polycarbonates, mixed with polyglycerols, [ (a-hydroxymethyl) oxyethylene/ (a-hydroxymethyl ethylene carbonate) copolymers; optionally [(a-alkyl) oxyethylene/ (a-alkyl) ethylene carbonate] copolymers, optionally [(a-alkyl) oxyethylene/ (a-hydroxyalkyl) oxyethylene] copolymers, glycerol carbonate and/or other organic carbonates, glycerol and/or other co-produced and/or residual compounds and a method for producing said composition. The inventive composition or the homopolymers and copolymers constituting same, are applicable in the technical fields of hydraulic fluids, lubrication, wood treatment and decoration, fire-retardant treatment, detergency, oil prospecting and production, water treatment, cosmetics, pharmaceutics, food industry and chemical intermediates.

L' invention concerne une composition organique comprenant des polycarbonates de glycérol, en mélange avec des polyglycérols, des copolymères [ (.alpha.- hydroxyméthyl) oxyéthylène/ (.alpha.-hydroxyméthyl éthylène carbonate) , éventuellement des copolymères [.(.alpha.-alkyl) oxyéthylène/ (.alpha.-alkyl) éthylène carbonate], éventuellement des copolymères [(.alpha.-alkyl) oxyéthylène/ (.alpha.-hydroxyalkyl) oxyéthylène], du carbonate de glycérol et /ou d'autres carbonates organiques, du glycérol et/ou d'autres composés coproduits et/ou résiduels et un procédé de production de ladite composition. La composition selon l'invention ou les homopolymères et copolymères la formant, trouvent des applications dans les domaines techniques des fluides hydrauliques, de la lubrification, du traitement et de la décoration du bois, de l'ignifugation, de la détergence, de l'exploration et de la production pétrolière, du traitement des eaux, de la cosmétique, de la pharmacie, de l'alimentaire et des intermédiaires de la chimie.
