Abstract
3-Methyl-1,3-pentadiene has been polymerized with the A(C 2 H 5 ) 2 Cl/Nd(OCOC 7 H 15 ) 3 /Al[CH 2 CH(CH 3 ) 2 ] 3 system to crystalline polymers consisting essentially of cis-1,4 units (≥ 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.
