摘要： 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 T.sub.g or T.sub.m of the polymer but below its degradation temperature.
