Abstract
The invention relates to a method for preparing a polyester polymer material, which comprises preparing a reaction medium comprising a mixture of at least one monomer chosen from ω-hydroxylated fatty acids and ω-hydroxylated fatty acid esters of an alcohol comprising an aliphatic chain comprising from 1 to 18 carbon atoms, and at least one phenolic compound, the total content of phenolic compound(s) being within a range of values from 0.3 to 42 mg equivalent of gallic acid per gram of the mixture. The method then comprises heating this reaction medium in order to carry out the polymerisation of the monomer and the phenolic compound and the cross-linking of the polymer thus formed.
