As a model case, they focused on glass transition temperature
, an index of heat resistance.
We conclude that the transport transition temperature
of acetone in PC arises from changes in the crystalline lattice.
where H represents the total enthalpy of PCM, [H.sub.0] is the sensible enthalpy, [DELTA]H is the latent heat, [beta] is the liquid fraction, and [T.sub.m] is the phase transition temperature
With its high glass transition temperature
and high crystallinity, the mechanical performance and the heat-aging performance of ForTii Ace are superior to rival polyphthalamides based on polyamides 6T, 9T and 10T.
Key statement: A rubber composition in which from 80 to 150 parts by weight of carbon black having a nitrogen adsorption specific surface area of from 200 to 400 [m.sup.2]/g is compounded per 100 parts by weight of styrene-butadiene rubber including from 60% to 100% by weight of solution-polymerized styrene-butadiene rubber S-SBR1 and from 40% to 0% by weight of solution-polymerized styrene-butadiene rubber S-SBR2 to result in a total of 100% by weight, the styrene quantity of the S-SBR1 being from 30% to 38% by weight, the vinyl quantity of the S-SBR1 being from 60% to 80% by weight, the glass transition temperature
of the S-SBR1 being from -20[degrees]C to -5[degrees]C, the weight-average molecular weight of the S-SBR1 being from 1.000.
They also wanted to correlate these characteristics to a variety of cheese properties, such as rheology, free oil, transition temperature
and water activity.
V[O.sub.2] has a tetragonal rutile structure with the P42/mnm space group (R phase) above the phase transition temperature
, where the partially filled [d.sub.//] band localized at the Fermi level and the rutile phase is metallic .
Shape memory polymer-based smart reversible adhesive systems are prepared by heating surfaces above their thermal transition temperature
, making them soft.
For short-term exposure, the main concern is often the softening as the thermoplastic approaches its glass transition temperature
(in the case of amorphous thermoplastics) or its melt transition temperature
(for semi-crystalline thermoplastics).
Table 1 presents the density, transition temperature
, thermal expansion, acoustic Debye temperature, and softening temperature of [(ZnO).sub.x][(Te[O.sub.2]).sub.1-x] zinc tellurite glasses.
The effect of [Eu.sup.3+] ion on phase, phase transition temperature
, and phase transition kinetics in the pseudoboehmite phase change process was investigated.
