That is, the compatibilizer has a structure in which a polymer chain composed of a fluoropolymer and a polymer chain composed of a non-fluoropolymer are bonded to each other. A block polymer is a polymer without a branched structure, and a graft polymer is a polymer with a branched structure.

[0095] The compatibilizer may contain at least one of a block polymer and a graft polymer, and may contain both, but preferably contains at least a block polymer.

[0099] Examples of the non-fluoropolymer in the non-fluoropolymer segment include those described above for the super engineering plastic resin, and the preferred forms are also the same.

[0100] The functional compound is not particularly limited as long as it is a compound having a functional group, and may be a polymer, an oligomer, or a low molecular weight compound other than these (for example, a monomer). In addition, the functional compound is preferably a compound having two or more functional groups.

[0101] The functional compound may be, for example, a monomer capable of forming an amorphous super engineering plastic resin. The monomer is preferably at least one selected from the group consisting of carboxyl group-containing compounds, amines, anhydrides, hydroxyl group-containing compounds, epoxy group-containing compounds, sulfhydryl group-containing compounds, siloxanes, and oxazoline group-containing compounds, more preferably at least one selected from the group consisting of acid anhydrides and diamines, and even more preferably at least one selected from the group consisting of 4,4'-(hexafluoroisopropylidene)diphthalic anhydride (6FDA) and 4,4'-oxydianiline (ODA). A combination of 6FDA and ODA is particularly preferred. The functional compound may also be a (co)polymer thereof.

[0102] In the compatibilizer, the functional compound may or may not be bonded to a block polymer or a graft polymer, but is preferably bonded. That is, the compatibilizer preferably contains a block polymer or a graft polymer in which a fluoropolymer segment, a non-fluoropolymer segment, and a functional compound are bonded. The compatibilizer may also contain a functional compound bonded to a block polymer or a graft polymer, and a functional compound that is not bonded.

[0103] In the above compatibilizer, the content of the fluoropolymer segment is preferably 50% by mass or more, more preferably 60% by mass or more, even more preferably 70% by mass or more, and is preferably 95% by mass or less, more preferably 90% by mass or less, even more preferably 85% by mass or less.

[0109] In step 2, the functional compound may be added in portions. This suppresses aggregation of the functional compound, resulting in a compatibilizer with excellent dispersion stability. Furthermore, for example, when 6FDA and ODA are used in combination, 6FDA may be added first and kneaded, followed by the addition of ODA. Adding ODA later can suppress deterioration of PEI and the like due to ODA.
