In this fourth paper, a new method for the preparation of polyglutarimides was studied. In order to avoid the use of a free amine at high temperature and contrary to the classic imidization reaction from PMMA and cyclohexylamine or methylamine, the amine function was introduced in the backbone on the polymer thanks to ammonium salts. They were incorporated by radical copolymerization between methacrylic monomers (methyl methacrylate, methacrylic acid) and cyclohexylammonium methacrylate or by salification of a methacrylic acid homopolymer with cyclohexylamine. After a thermal treatment at 250°C, the properties of these (co)polymers were compared (composition, glass temperature transition) with the materials obtained from the classic method.
