Abstract
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.
