What is The Crystal Structure of Trans Polyalkenamers about?
The structure of crystalline trans polyheptenamer [--CH~--------CH--(CHz)y--]tt has been determined by the X-ray diffraction spectra given by cold drawn fibres. The fibre repeat is 17.10 A and comprises two chemical units. The unit cell is orthorhombic, with two chains per cell. The cell dimensions are: a = 7-40 A; b = 5.00 A; c = 17"10 A; space group D~6 (p n a m). The a and b axes and the packing of the chains of trans polyheptenamer are very similar to those found for crystalline trans polypentenamer [--CH~CH--(CH2)3--]n and for orthorhombic polyethylene. The carbon atoms of the polymeric chain lie on two separate planes, running parallel to the chain axis. A different crystalline modification of trans polyheptenamer has been observed in some i.r. spectra.
