The effects of storage methods and glycerol on the aging of breadcrumbs were studied using solid-state (13)C CP/MAS NMR. After baking, a shift in C(1) peaks from triplet (A-type) to singlet (V-type) was observed. Addition of glycerol reduced the carb

The mutual miscibility diagram is determined for binary blends of two ethylene/norbornene random copolymers, and their monomer sequence distribution is investigated by 13C NMR spectroscopy. The miscibility changes abruptly at a norbornene content of
