Notes:
The crystal structure of the form I of syndiotactic poly(1-butene) is presented. According to the present analysis, chains having s(2/1)2 helical conformation are packed in an orthorhombic unit cell with a = 16,81 Å, b = 6,06 Å and c = 7,73 Å. The density is 0,96 g/cm3 with two chains in the cell (8 monomeric units), the space group is C2221. Disorder, corresponding to the statistical presence of right- and left-handed helices in each site of the lattice, could be present. The space group for the completely disordered structure is Cmcm.
