Abstrakt: A chemically cross-linked version of polystyrene is presented here that allows the preparation of reversibly mechanically compressible gels as NMR weakly aligning media. The gels can be successfully swollen in aromatic solvents such as toluene-d 8 and pyridine-d 5 , as well as in CDCl 3 , and provided accurate measurements of 1 D CH RDCs and 13 C-RCSAs.
