✦ Synopsis
Cross-polarization spectra of xenon adsorbed in a polymer blend with a polypropylene matrix and a polyethylene-propylene copolymer have been obtained. The temperature dependence of the magnetization transfer from 'H to lz9Xe is shown and a 2D 'H-'29Xe correlation spectrum is presented. From the spectra we can say that at the applied temperature (243 K) only xenon adsorbed in the polypropylene matrix gives a CP signal, not the xenon adsorbed in the more mobile copolymer phase.

It is demonstrated that xenon can be used as a tracer for the extraction of structure information in microheterogeneous amorphous polymer systems by means of two-dimensional NMR spectroscopy. lZ9Xe nuclei act as probes for structural heterogeneity. Experiments were performed on two model blends cons
