Clathrates with tetrahydrofuran of styrene-p-methyl styrene co-syndiotactic copolymers

Clathrates with tetrahydrofuran of styrene‐p‐methyl styrene co‐syndiotactic copolymers have been characterized by wide‐angle X‐ray scattering and differential scanning calorimetry. Stable clathrate structures with THF molecules have been observed in whole range of composition. In particular, syndiot...

Zusammenfassung:Clathrates with tetrahydrofuran of styrene‐p‐methyl styrene co‐syndiotactic copolymers have been characterized by wide‐angle X‐ray scattering and differential scanning calorimetry. Stable clathrate structures with THF molecules have been observed in whole range of composition. In particular, syndiotactic polystyrene like and syndiotactic poly‐p‐methylstyrene like clathrate phases are obtained for p‐methylstyrene contents lower and higher than 35% by mol, respectively.
