The Dependence of the Setting Temperature on the Concentration of Plasticizer

Abstract:

The theoretical analysis regarding the influence of the chemical structures both of polymer and plasticizer on the glass transition temperature has been produced. The analysis is made based on the Askadskii equation allowing T_g calculation of polymers. The phenomenon of blocking polar groups of the polymer by the molecules of plasticizer is taken into consideration. Also the effect of dilution was considered. The analytical expression for concentration dependence of the glass transition temperature is obtained, and a good agreement between the experimental and calculated data is provided.
