Maxima of degree of polymerization in equilibrium systems

Die Makromolekulare Chemie, 1963
AbstractPlots of the degree of polymerization vs. temperature may show maxima in systems polymerizing under equilibrium conditions. It is shown that an equation correlating the temperature at which the maximum occurs with the thermodynamic constants of the polymerizing system, which was previously developed for the autoinitiated polymerization of ...

Degree of polymerization of the CaAl2Si2O8 aluminosilicate glass

Glass Physics and Chemistry, 2006
The pressure dependence of the refractive index for a glass of the composition 0.50SiO2 · 0.25Al2O3 · 0.25CaO at pressures up to 5.0 GPa is determined using a polarizing interference microscope and an apparatus with diamond anvils. The densities and compressibilities of the glass are calculated from the measured refractive indices within the framework ...

Degree of Polymerization of Aluminosilicate Glasses and Melts

Glass Physics and Chemistry, 2004
This paper presents the results of analyzing the data available in the literature on the structure and properties of silicate glasses and melts that contain Ti4+, Al3+, and Fe3+ cations in addition to alkali and alkaline-earth cations. It is established that the aforementioned multivalent cations in glasses and melts have a coordination number of four ...

Effect of crystallinity and degree of polymerization of cellulose on enzymatic saccharification

Biotechnology and Bioengineering, 1984
AbstractLignocellulose materials were pretreated by methods known to improve enzymatic saccharification, and the percentage crystallinity (x‐ray diffraction) and degree of polymerization were measured. It was observed that although the percentage crystallinity of cellulose was not altered by alkaline explosion (AE), carbon dioxide explosion (CE), ozone,
