## Abstract The ^1^H and ^13^C NMR spectra of an alternating ethene/maleic anhydride copolymer and the corresponding acid and sodium salt were reinvestigated with regard to the signals depending on the configuration of the succinyl unit. From these assignments a 85/15 ratio of __threo__‐and __eryth

A set of model compounds that mimic the graft sites of maleic anhydride (MA) functionalized polyolefins was synthesized and characterized with NMR spectroscopy. The acquired carbon nuclear magnetic resonance data were used to deduce chemical-shift increments for the prediction of 13 C chemical shift

The pK, values of the succinic acid moieties of hydrolyzed alternating ethene-and isobutenemaleic anhydride copolymers were determined in D,O. The pD-dependence on the 13C chemical shift of selected signals was analyzed for these copolymers. Four different pK,s were determined for the copolymer with

The 'H and I3C NMR spectra of an alternating isobutene/maleic anhydride copolymer and the corresponding acid and sodium salt forms were reexamined by 1D and 2D NMR methods. This copolymer contains only threo-succinyl units. The tacticity is characterized by a 53/41 ratio of threo-diisotactic and thr
