R2 = l2 n ∑ i = 1C ′ (i) = Cnnl2 , where Flory’s characteristic ratio Cn is the average value of C ′ (i) over all backbone bonds of the chain. In general, Cn depends on n, but for very long chains it converges to a value C∞. WebSep 12, 2024 · At the glass transition temperature, the physical nature of the material changes subtly. It goes from being a rubbery, flexible material at higher temperature, above the glass transition, to a glassy, harder material at a lower temperature. The material is still a solid either way, but there is a definite change in how it responds to stimuli.

WebThe Flory-Fox equation (1,2) is the most popular empirical equation that relates the number-average molecular weight, Mn, to the glass transition temperature, Tg, Tg ( Mn) ≈ Tg,∞ - K / Mn. Another simple empirical formula for the prediction of the molecular weight dependence of the Tg has been developed by Fox and Loshaek: 3. WebMacromolecules are long repetitive sequences of an elementary chemical structure called the monomer (Fig. 6.12.1 ). The backbone of this long chain is mainly composed of carbon atoms linked together, and since the angle between two carbon atoms has a fixed value, successive atoms are located at only partially random positions.
