PMMA is completely amorphous and has a glass transition temperature of approx. 105 C. The first measurement curve is nearly always influenced by relaxation phenomena. If the thermal history is eliminated, the shape of the DSC curve becomes more or less ideal. In the curve shown above, the rel...
The glass transition temperature(Tg) of PMMA was tested by thermal mechanical analysis(TMA),and the influences of the heating rate and load on Tg of the PMMA plate were investigated.The results show that the value of Tg of PMMA increases with the increasing of heating rate;the load will aff...
Glass transition temperature of PMMA/modified alumina nanocomposite: Molecular dynamic study To attain this goal, the glass transition behavior of poly methyl methacrylate (PMMA), PMMA/alumina and PMMA/hydroxylated alumina nanocomposites were investigated by molecular dynamic simulations (MD). All the MD...
The interfacial effect is one of the significant factors in the glass-transition temperature (Tg) of the polymeric thin film system, competing against the free surface effect. Herein, the Tgs of poly (methyl methacrylate) (PMMA) films with different thicknesses and substrates are studied by fluor...
For a defined grade, the glass transition temperature increases from 50 °C during post cure. • A low-temperature curing grade with a cure time of less than 5 minutes at 80 °C has a glass transition temperature of about 140 °C. ...
The glass transition behaviors of ultrathin polymer shells deposited onto the surface of rodlike CaCO3 particles (whisker) have been studied, and no Tg deviations from the bulk for both polystyrene and poly(methyl methacrylate) (PMMA) shells without crosslinking were found.12 The case for their...
We have made ellipsometry and local thermal probe measurements of the glass transition temperature of thin films of blends of PMMA and PMMA-OH on SiO2 and HMDS substrates. A very small molar fraction of PMMA-OH (10 found to dramatically increase the Tg of the film to nearly the values corrs...
Effects of Residual Solvent on Glass Transition Temperature of Poly(methyl methacrylate) The effects of residual solvent on the glass transition temperature (T _(g) ) of poly(methyl methacrylate) (PMMA) were studied. A small amount of sol... A Ito,V Ayerdurai,CM Yamaguchi - 日本レオロジ...
