Claims
- 1. A continuous polymerization method comprising:
- supplying continuously a material solution for polymerization into a clearance between an inner cylinder and an outer cylinder of a coaxial double cylinder from one end side of said coaxial double cylinder,
- an axis of said coaxial-double cylinder stretches toward a direction crossing a horizontal plane;
- carrying out continuously an emulsion polymerization or a suspension polymerization while rotating at least one of said inner cylinder and said outer cylinder round said axis;
- rotating said inner cylinder at an angular velocity relative to said outer cylinder sufficient to produce Taylor vortices;
- a production of said Taylor vortices occurring when a Taylor number is about 30 to 2,000, wherein said taylor number is a function of a radius of said inner cylinder, a radius of said outer cylinder, a dynamic viscosity of said material solution and said angular velocity; and
- leading continuously a reaction solution containing a produced polymer from the other end side of said double cylinder to an outside and thus, obtaining polymer particles continuously.
- 2. The polymerization method according to claim 1, wherein the material solution for polymerization contains water, a polymerizable monomer, an emulsifier, and a water-soluble initiator.
- 3. The poolymerization method according to claim 2, wherein the material solution for polymerization contains nucleus particles for polymerization obtained from an emulsion polymerization reaction of a part of the material for polymerization beforehand.
- 4. The polymerization method according to claim 1, wherein the material solution for polymerization contains water, a polymerizable monomer, a dispersion stabilizer, and an oil-soluble initiator.
- 5. The polymerization method according to claim 4, wherein the material solution for polymerization is supplied as a material-suspended solution obtained by dispersing a part or the whole of the material for polymerization beforehand in water.
- 6. The polymerization method according to claim 1, wherein the material solution for polymerization is supplied from a lower end side of the double cylinder and the reaction solution is led from an upper end side of the double cylinder to an outside.
- 7. The polymerization method according to claim 1, wherein the material solution for polymerization is of heated and cooled from an outside of the double cylinder.
- 8. The polymerization method according to claim 1, wherein the at least one cylinder is rotated is the inner cylinder.
