<p>A method for preparing isotactic poly-1-butene. The method comprises: adding a nucleating agent in a bulk polymerization reaction kettle with 1-butene, and performing bulk polymerization on 1-butene by using a Ziegler-Natta catalyst system. By means of the method, the crystallinity of the poly-1-butene is improved, the crystallization rate is improved, the shock resistance performance is improved, and the time of transiting the crystal form II to the crystal form I is shorted.</p> |
