Influence of the guest molecules on the structural organization of the clathrates of syndiotactic poly(p-methylstyrene)

The influence of the shape and size of guest molecules on the structural organization of the α and β class clathrates of syndiotactic poly(p-methylstyrene) is described, through the analysis of the packing model proposed for the crystal structures of the clathrate forms containing o-dichlorobenzene and tetrahydrofuran. Preliminary data of the crystal structure of the s-PPMS clathrate containing benzene and a comparison with the crystal structure of the clathrate forms of syndiotactic polystyrene are also presented.
