発明の名称 (英語) Synthetic polymers controlled in spiral structure, host-guest compounds prepared by using the same, and processes for production of both UPDATE
発明の概要(英語) (US8383717)
The invention provides a process for producing spiral polymers controlled in the direction of spiral winding easily from inexpensive general-purpose polymers; and spiral polymers controlled in the direction of spiral winding.
The invention relates to a process for the production of syndiotactic polymethacrylate- or polyacrylate-type spiral polymers controlled in the direction of spiral winding which comprises dissolving a syndiotactic polymethacrylate- or polyacrylate-type polymer and a chiral compound in a solvent preferably under heating, subjecting the obtained solution to cooling or concentration to form a solid matter, and separating the solid matter; and so on.
特許請求の範囲(英語) [claim1]
1. A syndiotactic polymethacrylate or syndiotactic polyacrylate spiral macromolecular compound that is controlled in the direction of winding of the spiral structure, wherein a syndiotactic triad content (rr content) is 80% or more.
[claim2]
2. The spiral macromolecular compound according to claim 1, wherein the syndiotactic polymethacrylate polymer is syndiotactic polymethyl methacrylate.
[claim3]
3. The spiral macromolecular compound according to claim 1 produced by the process comprising: dissolving in a solvent a syndiotactic polymethacrylate or syndiotactic polyacrylate polymer of which a syndiotactic triad content (rr content) is 80% or more and a chiral compound in an amount 10% or more by volume with respect to said solvent; and
subsequently subjecting the obtained solution to cooling or concentration to form a solid matter.
[claim4]
4. The spiral macromolecular compound according to claim 1, wherein absorption circular dichroism is observed by measuring the circular dichroism (CD).
[claim5]
5. The spiral macromolecular compound according to claim 1 having unidirectionally wound spiral structure wherein direction of winding is controlled in either clockwise or counterclockwise.
[claim6]
6. The spiral macromolecular compound according to claim 5, wherein the syndiotactic polymethacrylate polymer is syndiotactic polymethyl methacrylate (st-PMMA).
