Procedure for the preparation of a thermally stable composition, characterized in that it is constituted from a solid polymer or copolymer of high molecular weight, which contains recurring -CH2O- units in the polymer chain and an amount of between 0.001 and 15 % weight of the polymer, of a stabilizer taken from the group consisting of the compounds of the general formula 1 **(See formula)** where X is a sulfur or oxygen atom or -NH or NR'' (where R'' is an alkyl, isoalkyl, aryl, or aryl substituted with NH2 or OH groups), R is a hydrogen atom or a NH2 or SH group and R'is a hydrogen atom or a -SH, NH2, -SO2NH2, NHR''' or -SO2NHR'''/ where R''' is an alkyl, isoalkyl, aryl or aryl substituted with groups NH2 or -OH), or of compounds of the general formula II **(See formula)** where X is a sulfur or oxygen atom, or a group -NH or N'(where R' is an alkyl, isoalkyl, aryl or a substituted aryl in which the substituents can be -NH2 or -OH groups), R is a hydrogen atom or -SH, NH2, SO2NH2, NHR'' or SO2NHR'' (where R'' is an alkyl, isoalkyl, aryl or substituted aryl in which the substituents can be groups - NH2 or OH) or -SS-R'''(where R''' is a benzoimidazene or benzothiazene radical.
