PROBLEM TO BE SOLVED: To obtain the subject composition capable of being uniformly and minutely dispersed and mixed, and having the characteristics of both polymers by dispersing and mixing a polymer having a high content of fluorine and a non-fluorinated polymer by using a specific dispersing agent. SOLUTION: This composition comprises (A) 2-90 pts.wt. fluorine-containing polymer having >=65 wt.% fluorine content [preferably a copolymer of tetrafluoroethylene and a perfluoro(alkyl vinyl ether) or the like], (B) 98-10 pts.wt. polymer not containing the fluorine (preferably a polyetherimide) and (C) 1-35 pts.wt. fluorinated compound containing a functional group having carboxylic acid group or sulfonic acid group as the functional group in a molecule (e.g. perfluoroalkylcarboxylic acid and perfluoroalkyl ether carboxylic acid) in 100 pts.wt. composition. The composition is obtained by melting and mixing the components, and can provide a molding product excellent in mechanical strength and elongation. |
