NEW NANOPOROUS CRYSTALLINE FORM OF SYNDIOTACTIC POLYSTIRENE, PROCESSES FOR ITS PREPARATION AND RELATED MOLECULAR-COMPLEX CRYSTALLINE FORMS

摘要

The present invention relates to a process for preparing a new nanoporous crystalline form of syndiotactic polystyrene, to the thus obtained crystalline form, to molecular-complex crystalline phases obtained by exposition of such crystalline form to low-molecular-mass molecules, and to the related processes for their preparation.
