Different solvent stability of the crystalline polymorphic forms of syndiotactic polystyrene

Understanding at molecular level of nanoporous and co-crystalline materials based on syndiotactic polystyrene

“…4. In addition to powders in d form, powders in the b crystalline form, which absorb low-molecular-mass compounds only into the amorphous phase [4,70,71], are also considered.…”

Polymorphism of syndiotactic polystyrene: γ phase crystallization induced by bulky non-guest solvents

“…indicated as G 0 in Fig. 1) at high concentrations also induce the formation of molecular complexes [16,29,30]. On the other hand, other guest molecules (e.g.…”

Evaluation by Fourier Transform Infrared Spectroscopy of the different crystalline forms in syndiotactic polystyrene samples

“…In partic-b, or mixed) depends on the crystalline structure sorption of suitable solvents (e.g., chloroform) produces transformation from a form toward the of the starting material 6,11 : if the starting material is in the b form, b form crystals are always clathrate d form [35][36][37][38][39][40] while it leaves unaltered the b form. 41,42 obtained; if the starting material is in the a or g form, the produced material is in the aЉ or b form…”
