摘要：

3-Methyl-1,3-pentadiene has been polymerized with the Al(C2H5)(2)Cl/Nd(OCOC7H15)(3)/ Al[CH2CH(CH3)(2)](3) system to crystalline polymers consisting essentially of cis-1,4 units (greater than or equal to 80%). NMR examination has shown that the polymers have an isotactic structure. This conclusion was confirmed by X-ray analyses, which further indicated that cis-1,4 isotactic poly(3-methyl-1,3-pentadiene) exists in polymorphic modifications.
