摘　　要：trans 1,4 Polybutadiene(PTBD) was synthesized by rare earth catalyst system. The effect of electron radiation on phase transition from monoclinic phase to hexagonal phase was observed by TEM. Electron diffraction patterns of monoclinic phase, hexagonal phase and two coexistent phases were recorded. The mechanism of phase transition was also discussed in this paper.trans 1,4 Polybutadiene(PTBD) was synthesized by rare earth catalyst system.
