摘要
Propene and 1-butene have been copolymerized in the presence of the catalytic system TiCl3/ A1(13CH2CH3)3. The results of13C NMR analysis of chain end groups in isotactic fractions of different composition provide stereochemical evidences of the inhomogeneity of the isotactic sites. © 1990, American Chemical Society.
