✦ Synopsis

Abstract

3‐Methyl‐1,3‐pentadiene has been polymerized with the Al(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.
