Both the glass transition temperature and the melting point of poly(vinyl chloride have been found to increase as the temperature at which the ample is polymerized is decreased). The glass transition temperature changes from about 70°C. for polymer prepared at 125°C. to about 100°C. for ...

a) a hydrophobic agent that does not cause any significant color change, nor impart any discoloration to a fabric, characterized as having a melting point or glass transition temperature of less than 100° C.; b) a fluoropolymer; and c) an effective amount of a zeta potential modifier; such...
A fabric treatment composition that includes at least one zeta potential modifier and a hydrophobic agent with a melting point or glass transition temperature below 100掳 C. that imparts fabric protection benefits, including improved stain and soil resistance, oil repellency, water repellency, softness...
Crystallizable polymers which can be cooled sufficiently fast below their melting point without crystallizing will also exhibit such a transition (Young and Lovell, 1991). The temperature at which the glass transition occurs is known as the Tg. The glass transition itself is not sharp, and ...
Determination of the glass transition temperature: (A) by dilatometry as the point of intersection of the temperature dependences of the glass and the melt; (B) by DSC on heating as the temperature of half unfreezing. Points 1, 2, 3, 4, 5, and 6 show the position of the points that...
b Transition of crystalline ZW-UiO-67·HA to glassy agZW-UiO-67·HA, then back to crystalline agrZW-UiO-67·HA through melting, quenching and solvent stimulation processes. The purple sphere and gray bond denote the Zr6O4(OH)4 node and BPDC-MIMS linker (BPDC = biphenyl-4,4’-...
When the sample’s temperature is close to the glass transition point (Tg, ~640 K) of the alloy, the as-sputtered MGNs start to relax to a more spherical shape (Supplementary Movie 9). The morphology changes, driven by surface tension, indicate that the sputtered sample is comprised of...

Why is it that thermoplastics do not have a fixed melting or glass transition temperature?Glass Transition Temperature:The glass transition temperature is defined as the range of temperatures at which movement in the lattice structure takes place. That is, where the transition...
