Abstract
PURPOSE:To readily product a compound capable of providing a high-quality and heat-resistant crystal high polymer, etc., by dispersing and blending a thick malt syrupy - rice caky substance containing a polybenzo-oxy or thio-azole precursor in a specific solvent. CONSTITUTION:A thick malt syrupy - gummy - rice caky substance consisting of a polybenzo-oxy or thio-azole precursor and polyphosphoric acid is dispersed in a solvent inert to phosphoric acid, the polyphosphoric acid and phosphoric anhydride and blended at 100-300 deg.C. An inert solvent selected from hydrocarbon oils, phenols, silicone oil, etc., is used as the inert solvent. Polyphosphoric acid containing phosphorous acid or ester thereof is used as the polyphosphoric acid.
