In summary, Fig. 6 exhibits the four characteristic temperatures of glass formation the Arrhenius temperature 7a, the crossover temperature Tj, the ideal glass transition temperature Tb, and a kinetic glass-formation temperature Tg (dehned in Section VI), to illustrate their relative locations with respect to the temperature variation of s. ... [Pg.159]

Dichroma.te(VI) Glasses. Alkali dichromate(VI) glasses exist in systems such as Li2Cr20y—Na2Cr20y. The glass-transition temperatures of the dichromates are very low, about 0°C. The addition of chlorides or nitrates aids in glass formation. [Pg.331]

Mixtures of monomers can be used to balance properties. This is possible due to the ease of copolymer formation via free-radical polymerization. The glass transition temperature of acrylic copolymers can be predicted from the weight fraction of the component monomers and the glass transition temperatures of the respective homopolymers [20]. Eq. 3 (commonly known as the Fox equation) is reported ... [Pg.830]

The addition of comonomers during the polymerization enables a higher flexibility compared to PVAc-homopolymerizates. This results in a lower glass transition temperature and a lower minimum temperature of the film formation. Possible comonomers are acrylic acid esters (butylacrylate, 2-ethylhexylacrylate), dialkylfumarates, ethylene and others. [Pg.1078]

The thermal behavior of many ionic liquids is relatively complex. For a typical IL, cooling from the liquid state causes glass formation at low temperatures solidifica-... [Pg.43]
