摘要： PURPOSE:A slurry composition that is prepared by dispersing a specific prepolymer resulting from reaction between butanetetracarboxylic acid and an aromatic primary diamine in water into fine particles, thus giving high heat-resistant formed products when used for impregnation and formed. CONSTITUTION:1,2,3,4-Butanetetracarboxylic acid is made to react with an equimolar amount of an aromatic primary diamine as m-phenylenediamine or 1,8-diaminonaphthalene in an organic solvent or water to form a prepolymer having more than 40% imidization rate, preferably more than 60%, a number-average polymerization degree of 1.5-10. Then, the resulting prepolymer is added to a prescribed amount of water (an organic solvent may be combined in an amount of less than 20 wt% based on the polymer solid part) and they are mixed under milling with a ball mill or oscillating mill to form said slurry compositon containing prepolymer particles with average particle sizes of 1-150 microns and having a viscosity of 1-100 poise.
