    • The present invention relates to a method for synthesising poly(alkoxyamine amide)s, in which the monomer chain has at least one thermolabile bond between monomers, wherein said method consists of reacting, on a solid or soluble substrate, an acid monomer in the form of a monohalogenated carboxylic acid of formula X-C(R,R')-Y-COOH with an amine monomer having a free terminal free-radical nitroxide group >N-O° and a free terminal primary amine group -NH
      2 , by performing two separate and chemically selective chemical reactions, one of which consists of reacting the aforementioned -COOH and -NH
      2 groups such as to obtain an amide bond -NH-CO-Y-C(R, R')-, and the other of which consists of reacting the -Y-C(R, R')° free-radical, obtained on site by means of a catalyst adapted to said halogen element X, with said nitroxide function >N-O° in order to obtain an alkoxyamine bond -Y-C(R, R')-O-N N-O° and a free terminal primary amine group -NH
      2 which is identical to or different from the preceding free-radical amine monomers, until obtaining the desired complete copolymer chain. The invention also relates to the polymers obtained and to the uses thereof.
