I found the field of Polymer Science very interesting. Saw the article Guest induced transition from beta to alpha nanoporous crystalline forms of PPO published in 2020. Safety of Benzyl ether, Reprint Addresses Guerra, G (corresponding author), Univ Salerno, Dipartimento Chim & Biol, Via Giovanni Paolo II 132, I-84084 Fisciano, Italy.. The CAS is 103-50-4. Through research, I have a further understanding and discovery of Benzyl ether
The stability of a and beta nanoporous-crystalline (NC) forms of Poly(2,6-dimethyl-1,4-phenylene) oxide (PPO), in the presence of guest molecules leading to crystallization in a and beta-form (alpha and beta-guests), is explored. Sorption of liquid guests at 30 degrees C and 60 degrees C is studied both for NC films and NC aerogels. WAXD and FTIR characterizations show that, for all considered conditions, NC alpha-phases after guest sorption/desorption remain unaltered. NC beta-phases, on the contrary, after alpha-guest sorption can be transformed in co-crystalline (CC) alpha-phases that after guest desorption are transformed in NC alpha-phases. All conducted experiments also show that possible planar orientations of NC films (c//or c perpendicular to orientations) remain essentially unaltered, after sorption of all considered guest molecules. The presently discovered beta ->alpha transition constitutes a route to obtain unoriented alpha-form films, which till now were not available by known preparation procedures.
