That is, the compatibilizer has a structure in which polymer chains composed of fluoropolymers and polymer chains composed of non-fluoropolymers are bonded together. Block polymers are polymers that do not have a branched structure, and graft polymers are polymers that have a branched structure.

[0095] The above-mentioned compatibilizer may contain at least one of a block polymer and a graft polymer, or both, but it is preferable that it contains at least a block polymer. Furthermore, the above-mentioned compatibilizer may also contain fluoropolymers and non-fluoropolymers that do not constitute block polymers or graft polymers (i.e., are not bonded to these polymers).

[0099] Examples of non-fluoropolymers in the non-fluoropolymer segment include those described above for super engineering plastics, and the preferred form is similar.

[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 other low-molecular-weight compound (e.g., a monomer). Furthermore, the functional compound is preferably a compound having two or more functional groups.

[0101] As functional compounds, for example, monomers capable of constituting amorphous super engineering plastic resins can be used. 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), and it is particularly preferable to use 6FDA and ODA in combination. Furthermore, the functional compounds may be (co)polymers of these compounds.

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

[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 also preferably 95% by mass or less, more preferably 90% by mass or less, and even more preferably 85% by mass or less.

[0104] In the above compatibilizer, the content of the non-fluoropolymer segment is preferably 5% by mass or more, more preferably 10% by mass or more, even more preferably 13% by mass or more, and also preferably 50% by mass or less, more preferably 40% by mass or less, and even more preferably 30% by mass or less.

[0107] The above-mentioned compatibilizer can be prepared by, for example, step 1, which involves kneading the fluoropolymer in a twin-screw extruder or the like to apply shear to the fluoropolymer and adjust the amount of terminal functional groups and MFR of the fluoropolymer, and step 2, which involves kneading the fluoropolymer after step 1, a non-fluoropolymer, and a functional compound.

[0108] In order to adjust the amount of terminal functional groups and MFR to a good range, it is preferable that the kneading in step 1 be performed at a kneading temperature of 200 to 400°C, a kneading time of 1 to 120 minutes, and a rotation speed of 100 to 3000 rpm.

[0109] In step 2, the functional compound may be added in divided form. This suppresses aggregation of the functional compound and yields a compatibilizer with excellent dispersion stability. Also, for example, when using 6FDA and ODA together, 6FDA may be added first and kneaded, and then ODA may be added. Adding ODA later can suppress degradation of PEI and other substances caused by ODA. From a similar perspective, when using FDA and ODA in combination, they may be reacted beforehand, and the resulting polyamic acid may be added. From the viewpoint of reactivity, the polyamic acid is preferably in the form of a dimer or oligomer.
