Above all, it is actively used as a packing material for chromatography columns for optical resolution. It is known that the optical resolution chromatography is extremely effective as an optical resolution means because the optically active substance can be easily and easily analyzed and fractionated. The following are examples of asymmetric recognition polymers that have been researched and developed as packing materials for chromatography columns for optical resolution. Cellulose triacetate (for example, JP-A-59-1665)
No. 02), cellulose benzoate (for example, JP-A-6
And polysaccharide derivatives such as cellulose carbamate (for example, JP-A-60-108751) and amylose carbamate (for example, JP-A-60-226831). Bovine serum albumin (for example, J. Chromato., 264 (1
983) 63-68), α-acid glycoprotein (for example, J. Chromat
o., 269 (1983) 71-80), and ovomucoid (for example, JP-A-4-187646). Poly (meth) acrylamide (for example, see
Synthetic polymer systems such as poly (meth) acrylate (for example, JP-A-56-142216). However, these asymmetric recognition polymers have advantages and disadvantages in optical resolution depending on the target compound, and the range of the target compound in each optical resolution has been limited. Therefore, an object of the present invention is to provide a novel optical resolving agent in order to widen the range of the target compound for optical resolution. [0005] The inventors of the present invention have been working on the application of a novel optically active polyacetylene derivative, which was previously filed as Japanese Patent Application No. 6-82843, in the course of application research. The present inventors have found that this polymer is useful for solving the problem, and have led to the present invention.

As described above, the present invention provides an optical resolution agent using an optically active polyacetylene derivative in which R * in the formula (I) is a group represented by the following formula (II). [0006] The optically active polyacetylene derivative according to the present invention has a chiral carbamoyl group represented by the above formula (II) in the side chain. The production of the optically active polyacetylene derivative in the present invention can be carried out by the method described in Japanese Patent Application No. 6-82843 filed by the present inventors. That is, 4- (dimethyl-t-butylsiloxy) -phenylacetylene is first desilylated and then reacted with an optically active isocyanate to synthesize a monomer represented by the formula (III). [0008] Next, this monomer is treated with [Rh (NBD) Cl] 2 (N

~ 50000Å. The method of supporting the optically active polyacetylene derivative according to the present invention on a carrier may be a chemical method or a physical method. As a physical method, an optically active polyacetylene derivative is dissolved in a soluble solvent, mixed well with a carrier, and then depressurized and heated, and the solvent is distilled off by an air stream, or the optically active polyacetylene derivative is dissolved in a soluble solvent. There is a method in which the resulting solution is mixed well with the carrier and then poured into an insoluble solvent to diffuse the soluble solvent.
