Notes:
Polymeric materials have been prepared by the reaction of the divalent Cu, Ni, Co, Zn, Cd, and Mg cations with the dipotassium salt of tetraacetylethane in methanol-water solutions. The polymers appear to be of low molecular weight and generally contain potassium in the endgroups. The insoluble, infusible, materials decompose on heating in the absence of air to give, among other products, H2, 3,4-diacetyl-2,5-dimethylfuran, and the free metal or metal oxide. The order of decreasing heat stability is Mg 〉 Ni 〉 Co 〉 tetraacetylethane 〉 Cu 〉 Zn 〉 Cd. The Cd chelate polymer decomposes appreciably at 225°C., while the Mg polymer, heated under the same conditions, begins to decompose at about 350°C.
