Claims
- 1. A curable polymer composition comprising:
- (A) an organic elastomeric polymer having, in a molecule, at least one silicon-containing group which is cross linkable through formation of a siloxane bond, said organic elastomeric polymer being selected from the group consisting of a polyether which includes repeating units of the formula --R--O-- in which R is a divalent alkylene group having 2 to 4 carbon atoms and a graft copolymer produced by polymerizing a vinyl monomer in the presence of said polyether, and
- (B) an epoxy resin which has been cured with a curing agent in the presence of a solvent in which an uncured epoxy resin and the curing agent can be dissolved, and wherein the cured epoxy resin is insolubilized to precipitate in the form of fine powder.
- 2. The curable polymer composition according to claim 1, wherein the weight ratio of the organic elastomeric polymer (A) to the epoxy resin which has been cured (B) is from 100:1 to 100:200.
- 3. The curable polymer composition according to claim 1, wherein the organic elastomeric polymer (A) has a backbone chain consisting of a polyether comprising repeating units of the formula: --R--O-- in which R is a divalaent alkylene group having 2 to 4 carbon atoms.
- 4. The curable polymer composition according to claim 1, wherein the organic elastomeric polymer (A) has a graft copolymer produced by polymerizing a vinyl monomer in the presence of the polyether.
- 5. The curable polymer composition according to claim 1, wherein the silicon-containing group which is cross linkable through formation of a siloxane bond is a silicon-containing group having an alkoxy group bonded to the silicon atom.
- 6. A curable polymer composition comprising:
- (A) an organic elastomeric polymer having, in a molecule, at least one silicon-containing group which is cross linkable through formation of a siloxane bond, said organic elastomeric polymer being selected form the group consisting of a polyether which includes repeating units of the formula --R--O-- in which R is a divalent alkylene group having 2 to 4 carbon atoms and a graft copolymer produced by polymerizing a vinyl monomer in the presence of said polyether, and
- (B) an epoxy resin which has been cured in the organic elastomeric polymer with a curing agent in the presence of a solvent in which an uncured epoxy resin an the curing agent can be dissolved.
- 7. The curable polymer composition according to claim 6, wherein the weight ratio of the organic elastomeric polymer (A) to the epoxy resin which has been cured (B) is from 100:1 to 100:200.
- 8. The curable polymer composition according to claim 6, wherein the organic elastomeric polymer (A) has a backbone chain consisting of a polyether which includes repeating units of the formula: --R--O-- in which R is a divalent alkylene group having 2 to 4 carbon atoms.
- 9. The curable polymer composition according to claim 6, wherein the organic elastomeric polymer (A) has a graft copolymer produced by polymerizing a vinyl monomer in the presence of the polyether.
- 10. The curable polymer composition according to claim 6, wherein the silicon-containing group which is cross linkable through formation of a siloxane bond is a silicon-containing group having an alkoxy group bonded to the silicon atom.
