dcterms:description
The high-resolution solid-state 13C and 1H NMR spectra, and 13C rotating frame spin-lattice relaxation times, were measured for metallocene (m) and Ziegler-Natta (ZN) isotactic polypropylenes (iPP) within the temperature range of 20–160°C. With the rise of temperature the splitting of CH2, CH and CH3 signals into two components was detected in 13C NMR spectra and assigned to amorphous and crystalline phases. The temperature dependences of chemical shifts and integral intensities obtained from the deconvoluted spectra provided information on the main chain and CH3 groups motions in amorphous and crystalline regions of studied samples. While values of relaxation times show that the rate of segmental motion in amorphous regions in m-iPP and ZN-iPP is virtually the same, larger linewidths in 13C and 1H NMR spectra indicate somewhat larger restraints of the motion in amorphous regions of ZN-iPP.
