Characteristics of solid state polycondensation

1. Compared with general polycondensation, the molecular weight and mechanical properties of solid-state polycondensation are obviously improved, which makes its products have a wide range of uses;

2. The reaction temperature is low, which effectively inhibits the occurrence of side reactions. The reaction temperature of solid-state polycondensation is lower than the melting point, and the activation energy of thermal degradation is higher, so the rate of side reactions such as thermal degradation in solid-state polycondensation will be greatly weakened with the decrease of temperature.

3. Low reaction energy consumption.

4. The process is environment-friendly and simple. In the process of solid-state polycondensation, there is no need to use solvents, and the reaction products do not need to be purified, and there is no solvent recovery, so the process is very environmentally friendly; In addition, the solid-state polycondensation reaction can be operated intermittently or produced continuously, so the choice of reactors is very wide.
