Publication number: 20220251289Abstract: A method for preparing a polymer of the elastomer type based on a monomer selected from polyhydroxylated fatty acids and esters of a polyhydroxylated fatty acid and a C1-C18 aliphatic chain alcohol is disclosed. This method includes preparing a reaction medium by bringing the monomer with a polyol, this reaction medium being catalyst free, then a step of heating the reaction medium in order to implement the copolymerisation of the monomer and of the polyol and the cross-linking of the polymer thus formed, with at least the initial phase of this heating step being implemented at a reduced pressure.Type: ApplicationFiled: June 23, 2020Publication date: August 11, 2022Inventors: Bénédicte BAKAN, Didier MARION, Denis LOURDIN, Mathilde MARC, Romain VALENTIN, Zéphirin MOULOUNGUI, Eric LEROY, Christelle LOPEZ

Patent number: 6316641Abstract: The invention concerns a method for preparing an epoxide, in particular glycidol, wherein a cyclic organic carbonate, in particular glycerol carbonate, is heated under reduced pressure so as to carry out a reaction to contract the carbonate ring into an epoxide ring. According to the present invention, the reaction is carried out in a solid/liquid system in the presence of a polyol and a solid catalyst consisting of a type A zeolite or &ggr;-alumina. The method, which may be carried out continuously, enables the epoxide to be formed in a single step, the epoxide being exhausted in the form of vapor which only has to be extracted and separated from the carbon dioxide formed.Type: GrantFiled: September 8, 1999Date of Patent: November 13, 2001Assignee: Organisation Nationale Interprofessionelle des Oleagineux (O.N.I.D.OL.)Inventors: Jeong-Woo Yoo, Zéphirin Mouloungui, Antoine Gaset
