The Description of Polycondensation of Glycolic Acid
There is a matter of polycondensation of glycolic acid today. Glycolic acid has special properties, and in the process of polycondensation, many factors are related to the result of its polymerization.

At the beginning, the temperature of the reaction is very important. If the temperature is too low, the kinetic energy of the molecules is insufficient, the frequency and strength of each other's collision are small, it is difficult to effectively form bonds between glycolic acid molecules, the rate of polycondensation is slow, and the chain length of the polymer is also limited; if the temperature is too high, although the molecular collision intensifies, it may cause side reactions, such as the decomposition of molecules, etc., and it is not conducive to the formation of the polymer. Therefore, when the temperature

times, the choice and amount of catalyst, left and right polycondensation. Appropriate catalysts can reduce the activation energy of the reaction, promote the interaction of functional groups of glycolic acid molecules, and increase the rate of polycondensation. However, if there are too many catalysts, or the reaction speed is too fast and difficult to control, if there are too few, the catalytic effect will not be obvious, all of which affect the quality and quantity of the polymer.

In addition, the reaction time cannot be ignored. The time is short, the polycondensation is not complete, and the molecular weight of the polymer is not up to expectations; the time is long, or the side effects such as chain breaking of the polymer will also damage its properties. Therefore, it must be stopped in time according to the reaction situation.

Glycolic acid polycondensation, in order to obtain a good polymer, it is necessary to precisely control the temperature, agent and time factors to achieve a good environment and obtain a suitable polymer.
