ABSTRACT The crystal structure of isotactic polystyrene is described in this paper. The unit cell as determined from the X-ray diffraction spectra of oriented samples is rhombohedral, and its constants referred to hexagonal axes are: a = 21.9 ± 0.1 A , c = 6.65 ± 0.05 A ( chain axis ) Z = 18 ; Space group R 3 c or R 3 ¯ c . 

Isotactic poly(p-fluorostyrene): X-ray structure determination

Abstract Using as a starting point the atomic positions determined by potential energy calculations, the crystal structure of isotactic poly(p-fluorostyrene) has been determined from X-ray

Conformation analysis of isotactic polystyrene

The potential conformational energy of isotactic polystyrene has been calculated as a function of the angles of rotation around the three non-equivalent bonds in the monomeric unit. The calculations

Crystal structure of isotactic poly (vinyl methyl ether)

The crystal structure of isotactic poly(vinyl methyl ether) has been defined on the basis of x-ray fiber spectra. Isotactic poly(vinyl methyl ether) crystallizes in a rhombohedral unit cell whose
