- 3. The process according to claim 1, wherein the active hydrogen-containing group is a hydroxyl group.
- 4. The process according to claim 1, wherein the functional group cross-linkable by the action of moisture is a group selected from the group consisting of an isocyanate group, a hydrolyzable silyl group and a thiol group.
- 5. The process according to claim 1, wherein the polyoxyalkylene chain is a polyoxyalkylene chain having from 5 to 50 oxyalkylene units.
- 6. The process according to claim 1, wherein the monomer having an .alpha.,.beta.-unsaturated group is a compound selected from the group consisting of a vinyl compound, an allyl compound, an acryloyl compound and a methacryloyl compound.
- 7. The process according to claim 1, wherein the polymerization is conducted to obtain a polymer comprising, based on entire polymer units, from 30 to 70 mol % of polymer units derived from the polyfluoroolefin and from 1 to 80 mol % of polymer units derived from the monomer having a polyoxyalkylene chain having, at its terminal, a group selected from the group consisting of an active hydrogen-containing group, an epoxy group and a functional group cross-linkable by the action of moisture and an .alpha.,.beta.-unsaturated group copolymerizable with the fluoroolefin, and the total of the two types of polymer units being from 30 to 100 mol %.
- 8. A process for producing a fluorine-containing copolymer having a polyoxyalkylene chain having a hydroxyl group at its terminal, which comprises adding an alkylene oxide to a fluorine-containing copolymer comprising, based on entire polymer units, from 20 to 70 mol % of polymer units (1) derived from a fluoroolefin and from 1 to 80 mol % of polymer units (3) having a functional group to which the alkylene oxide is to be added, the total of the polymer units (1) and the polymer units (3) being from 30 to 100 mol %.
- 9. The process according to claim 8, wherein the functional group to which the alkylene oxide is to be added, is a hydroxyl group.
- 10. The process according to claim 8, wherein the alkylene oxide is added in an amount of from 5 to 50 mols per mol of the polymer units (3).
- 11. A process for producing a fluorine-containing copolymer having a functional group cross-linkable by the action of moisture, which comprises reacting a fluorine-containing copolymer comprising, based on entire polymer units, from 20 to 70 mol % of polymer units (1) derived from a fluoroolefin and from 1 to 80 mol % of polymer units (4) having a polyoxyalkylene chain having a reactive group at its terminal, the total of the polymer units (1) and the polymer units (4) being from 30 to 100 mol %, and a compound having a functional group reactive with the reactive group of the fluorine-containing copolymer and a functional group cross-linkable by the action of moisture.
- 12. The process according to claim 11, wherein the polyoxyalkylene chain is a polyoxyalkylene chain having from 5 to 50 oxyalkylene units.
- 13. The process according to claim 11, wherein the functional group cross-linkable by the action of moisture is a group selected from the group consisting of an isocyanate group, a hydrolyzable silyl group and a thiol group.
- 14. The process according to claim 11, wherein the reactive group is a group selected from the group consisting of a hydroxyl group, a carboxylic acid group, an amino group, an acid amide group, a thiol group, an active halogen-containing group, an epoxy group and an ethylenically unsaturated group.
