Notes:
The structure of poly-1,3-dioxolane, [—OCH2O—(CH2)2—]n was studied by x-ray diffraction and infrared spectroscopy. Three crystal modifications were found. The crystal structure of modification II was determined: four molecular chains of glide type pass through the orthorhombic unit cell; Pbca-D2h15, a = 9.07 Å, b = 7.79 Å, and c (fiber axis) = 9.85Å. The molecular conformation is The molecular chain consists of regular head-to-tail sequences. This fact shows that the ring opening of 1,3-dioxolane occurs exclusively at the same type of CO bond in the cationic polymerization, just as in the case of 1,3-dioxepane.
