Abstract
PURPOSE: A polyimide resin solution in a phenolic solvent is mixed with a solution of a titanium organic chelate compound to recover the precipitating resin, thus producing inexpensively said heat-resistant resin powder for forming.
CONSTITUTION: (A) 100 parts by wt. of a polymide resin solution resulting from the reaction between aromatic tetracarboxylic acids containing more than 30mol% of 3,3', 4,4'-benzophenonetetracarboxylic acid and diamines containing 20mol% or more aromatic amines of formula IWIV (X is CH2, O,SO2, formula V, S; R is lower alkyl, lower alkoxy, carboxyl, halogen, hydroxyl, sulfonyl) are mixed with (B) 0.1W5 parts of a solution of a titanium organic chelate compound in a solvent that does not dissolve (A) and the resin precipitated is filtered, washed and dried. The amount of (A) is based on the resin part and that of (B) is calculated as titanium metal.
