## Abstract The crystal structure of polyketone (1:1 ethylene/carbon monoxide copolymer) obtained by Ξ³βirradiation copolymerization of ethylene and carbon monoxide was determined by xβray diffraction. An orthorhombic unit cell was found, having space group __D__ __(Pnam)__ of dimensions __a__ = 7.9
Kohlenforschung at MΓΌlheim an der Ruhr for their kind support and their help in performing the reactions in supercritical carbon dioxide. Preparation for the synthesis of polyketones in scCO 2 : Compound 4 e (5.5 mg, 0.006 mmol) was transferred to a 20-mL autoclave under N 2 . The solution was pres
