Phase-Transition in Ethylene-Tetrafluoroethylene (Etfe) Alternating Copolymer - A Spectroscopic Study
The study of temperature dependent infrared (i.r.) and Raman spectra of alternating ethylenetetrafluoroethylene (ETFE) copolymer suggests that the transition from orthorhombic to hexagonal phases may be driven by the generation and propagation of conformational solitons (gentle mobile chain twist).
