Highly porous aerogels were obtained from sPS physical gels by suprecritical carbon
dioxide based extraction procedure. During experimentation, in the clathrate phase, the …

Crystalline modifications, exhibiting largely different X-ray diffraction patterns, have been
obtained for poly (2, 6-dimethyl-1, 4-phenylene) oxide (PPO), by gel desiccation procedures …

The crystal structure of the molecular complex of syndiotactic polystyrene (s-PS) with bicyclo
[2.2. 1] hepta-2, 5-diene (norbornadiene, NB) is presented. In analogy to the already …

The crystal structures of two molecular complex phases of syndiotactic polystyrene (s-PS)
with 1, 3, 5-trimethyl-benzene (TMB) and 1, 4-dimethyl-naphthalene (DMN) have been …

Sorption of long aliphatic carboxylic acids (lauric with 12 C atoms and stearic with 18 C
atoms) and of an aliphatic dicarboxylic acid (adipic), by amorphous and nanoporous …

The self-assembling of fluorescent guest molecules, with the δ nanoporous host crystalline
phase of syndiotactic polystyrene (s-PS) films, reduces chromophore diffusivity. Moreover …

Semicrystalline syndiotactic polystyrene (s-PS) films, for all crystalline phases based on
helical chains (δ, γ and clathrates), have been prepared with high degrees of three different …

Selective absorption uptake during the guest‐exchange processes in the δ form of
syndiotactic polystyrene (sPS) was confirmed by IR spectroscopy. When films of the δ form …

The sorption and desorption of a guest (1, 2-dichloroethane) in syndiotactic polystyrene (s-
PS) films, presenting three different kinds of uniplanar orientation ((010),(2̄10), or (002)) of …

Monolithic and highly crystalline aerogels of isotactic poly (4-methyl-pentene-1)(i-P4MP1)
have been prepared by sudden solvent extraction with supercritical carbon dioxide from …
