1). The aromatic protons form an AA'BB' system and the three-membered ring protons and ABX system. The detailed analysis of both systems permits exact determination only of the parameters of the aromatic protons. Protons and coupling constants of the ABX system can be assigned on the assumption that
Copolymers of 7-oxabicyclo[2.2.1]heptane (B) (and of its 2-methyl derivatives) with 1,3-dioxane (D) were obtained by cationic copolymerization initiated with benzoylium hexafluoroantimonate. Structure of copolymers was determined by 1 H-and 13 C-NMR. The proportion of the acetal bonds in copolymers
