Abstract

The order-disorder phenomenon and spatial heterogeneity of chain packing, partitions of stereodefects, and molecular dynamics of α form of isotactic polypropylene (iPP) samples, which are synthesized by Zieglar-Natta catalysts, are investigated by solid-state (SS) NMR. High-resolution ¹³C NMR under high-power TPPM decoupling at field strengths of 110 kHz allows observation of the order-disorder phenomenon in the chain-packing structures of α form. High isotacticity samples (isotacticity at pentad level, âŸ̈mmmmâŸ
