WebApr 1, 2001 · The crystal transition mechanisms were investigated and well established in PBT [7] and in PTMS [13] as well as in poly (ethylene oxide) (PEO) [18]. These studies showed that these crystal transitions belong to the thermodynamic first-order phase transition. The mechanism accounted well for the observations: (1) The fraction of the β …

Crystals: In a transition to a crystalline solid a disordered liquid with non apparent structure undergoes a transition to a structure with long range periodic order, usually in three dimensions. This is most easily parametrized by the mass density, ρ(r): ρ(r) = ¯ρ+ X q∈G ρ(q)e−iq·r +c.c, (1) where ¯ρis the mean density and {G ... WebFeb 4, 2024 · The crystal transition takes place in the newly formed chain-extended crystals rather than the original crystals. The transformed β crystals can recover to their α counterparts upon annealing at high temperature when the stress is released. Supporting Information. ARTICLE SECTIONS. orb homography
