MELT-SHAPED BODY OF POLYIMIDE PRECURSOR AND PROCESS FOR PRODUCTION OF POLYIMIDE FOAM USING SAME |
摘要 |
<p>The object is to propose an improved process for the production of a polyimide foam by which a large-sized polyimide foam in a state of fine and homogeneous cells can be readily obtained by easy operations and convenient steps. A melt-shaped body of a polyimide precursor obtainable by melt-treating in a closed state a powder of a polyimide precursor including at least an aromatic tetracarboxylic acid ester component and an aromatic amine component. A process for the production of a polyimide foam including the steps of melt-shaping in a closed state a powder of a polyimide precursor including at least aromatic tetracarboxylic acid ester component and an aromatic amine component to give a melt-shaped body of the polyimide precursor, and foaming the melt-shaped body of the polyimide precursor by a heat treatment.</p> |
