Abstract
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.
