Is it possible which low-molecular weight polymer doesn't have Tg (glass transition temperature) ?
Mn around 936 gmol-1
All liquids which do not crystallize upon cooling should show a Tg. Examples are toluene, glycerol. A low MW polymer has a Tg given by the Fox&Flory eq.
Do we have any empirical model to model the combined effect of carbonation and chloride attack in concrete concerning time-dependent temperature, relative humidity and concentration of carbon dioxide?
