Disclosed is a method of making an imide-containing polymer by bulk or melt polymerizing monomers. A mixture is formed of (1) a cyclic compound that contains an anhydride group and a second group which is an anhydride, a carboxylic acid, or an ester and (2) a diamine in an amount stoichiometric +/- 5 mole% of stoichiometric with the amount of cyclic compound. An end capper may also be included in the mixture to control the molecular weight but no solvent is used. A polyimidesiloxane can be made by using a siloxane- containing diamine. The mixture is heated to a temperature above the Tg or Tm of the polymer but below its degradation temperature.

Cette invention a trait à un procédé de production de polymères renfermant un imide par polymérisation, en masse ou par fusion, de monomères. On prépare, à cet effet, un mélange composé, (1), d'un composé cyclique contenant un groupe anhydride ainsi qu'un second groupe qui est un anhydride, un acide carboxylique ou un ester et, (2), d'une diamine en proportion stoechiométrique de +/-5 mole en pourcentage de stoechiométrique avec la quantité de composé cyclique. Le mélange peut également comprendre une protection d'extrémité afin d'agir sur le poids moléculaire, mais l'on n'utilise pas de solvant. Il est possible d'obtenir du polyimidesiloxane en employant une diamine renfermant du siloxane. Le mélange est chauffé à une température supérieure au T¿v? ou au T¿f? du polymère mais inférieure à sa température de dégradation.
