2 Claims

1. A method for manufacturing a separating agent for optical isomers, comprising:

radical copolymerization of an amylose derivative having a first radically polymerizable group, a carrier having a second radically polymerizable group, and a radically polymerizable monomer,

wherein in the amylose derivative having the first radically polymerizable group, some of hydroxyl groups of amylose are replaced by 3-chloro-5-methylphenylisocyanate, while other hydroxyl groups are replaced by a substituent having the first radically polymerizable group,

wherein the first radically polymerizable group of the amylose derivative and the second radically polymerizable group of the carrier are the same or different.
