The procedure for the estimation of the ideal glass transition temperature has been reviewed together its importance in the glass forming ability of materials. The glass forming ability of undercooled materials is also explained in terms of ratio of reduced glass transition temperature and ideal glass...
where the parameter η∞describes the viscosity at T→ ∞ and α is the dimensionless fragility parameter. Tccharacterizes the temperature at which log η = 13 dPa ∙ s and is close to the experimentally measured glass transition temperature Tg. Results Nucleation rates and crystal...
To investigate the effect of the stoichiometry on the glass transition temperature, Tg, of an epoxy–amine system with excess of the amine or the epoxy. The stoichiometric ratio of amine to epoxy may be defined as r = |A|/|E|, where |A| and |E| are the number of gram-equivalents ...

The Glass Transition Temperature The glass transition, T g, is a phenomenon observed in linear amorphous polymers, such as poly(styrene) or poly(methyl methacrylate). It occurs at a fairly well-defined temperature when the bulk material ceases to be brittle and glassy in character and becomes ...

It can be shown that the polymer particle with the lower glass transition temperature T-g shows a stronger impact on cement hydration, which cannot be explained by any influence on the pore solution composition or the initial dissolution of cement phases. Hence, the adsorption mechanism seems to...
The Correlation between Reduced Glass Transition Temperature and Glass Forming Ability of Undercooled Polymeric Glasses The thermodynamic behaviour of glass forming undercooled melt have been studied by analysing the temperature dependence of the Gibbs free energy difference...
