%X How to excite the biexctions in a polymer is an essential subject, since the biexciton possesses an effect of photo\|induced polarization reversion. This paper proposes a new channel to produce the biexciton through two\|electron excitation. The relaxation processes of both lattice distortion and electronic states are simulated by studying its dynamics, and the relaxation time of biexciton formation and polarization reversion is determined.
