The Effect of Disperse Dyes on the Glass Transition Temperature of Polymers

The lowering of the glass transition temperature (Tg) of a polymer produced by the incorporating various concentrations of azo disperse dyes has been investigated, and the effects of the structure and concentration of the dyes were examined. The Tg values were lowered with increasing dye concentration in the polymer, and the lowering of Tg produced by the dyes was influenced not only by the molecular structure of the dyes but also the dye-polymer interactions
