We have reconfirmed the three unusual phenomena on the helix-sense-selective polymerization(HSSP) as gollows: 1) Spontaneous HSSP: The HSSP happened without any chiral cocatalyst. The best condition was a melt polymerization. 2) HSSP catalyzed by chiral polymers prepared by HSSP: The HSSP proceeded when the chiral polymers prepared by HSSP of the corresponding monomer. 3) Achiral-condition control HSSP: The helical sense of the chiral polymer prepared by HSSP was controlled by ahiral conditions. The mechanism was discussed by some spectra of the chiral catalytic system.
