Abstract
The copolymer obtained by radiation-induced copolymerization of hexafluoroacetone with ethylene at −78°C was examined by X-ray diffraction. The crystal data are: orthorhombic, P212121, a=10.63 A, b=8.00 A, c(fiber axis)=8.01 A, and two polymer chains pass through the unit cell. The copolymer was revealed to have an alternating structure of hexafluoroacetone and ethylene units. The molecular chain forms a (2/1) helix of essentially (TTTC)2 conformation. The internal rotation angles are as follows:
