The styrene sequence distributions and amount of reacted fumarate units in cured, unsaturated polyester resins were studied by solid-state 13 C nuclear magnetic resonance. Increasing the styrene content and molar ratio of styrene to the double bonds in the polyester chain increased the amount of dia

Benzoxazines derived from bisphenol-A, formaldehyde, and primary amines were characterized using 13 C solid-state NMR spectroscopy. The two 1,3benzoxazines studied in this work are 2,2Π-(3-methyl-4-dihydro-1,3,2-benzoxazine)propane, (B-m) and 2,2Π-(3-phenyl-4-dihydro-1,3,2-benzoxazine)propane (B-a).
## Abstract The ^13^C NMR chemical shifts in the solution and in the solid state and those of ^15^N and ^17^O and the line widths of the ^14^N and ^17^O resonance signals in the solution state were determined for carboxamides, aliphatic and aromatic sulphonβ and sulphinβamides and a thioamide (thio
