摘要

Polymer blends were prepared to obtain a new material with specific characteristics. To prepare a miscible polymer blend, it is necessary to evaluate the chemical structure and molecular dynamics of all polymers involved and to thereby establish a structure-property relationship for these materials. In this work, ternary blends for application in plates chromatography were formed with styrene/butadiene/acrylinotrile (ABS), poly(vinyl chloride) (PVC), and gypsum, and were studied by solid-state carbon-13 nuclear magnetic resonance (C-13 NMR). Magic-angle spinning (MAS), cross-polarization magic-angle spinning (CP-MAS), variable contact time (VCT), and proton spin-lattice relation time in the rotating frame (T(1)(H)rho) were the techniques used to evaluate the miscibility, homogeneity, and compatibility of polymer blends at the molecular level. From the values of T(1)(H)rho, it was verified that ABS/PVC/gypsum formed good polymer blends with some specific physical interaction at the molecular level. (C) 2003 Wiley Periodicals, Inc.
