Definitions

- Glycerol carbonate is described in EP328150. The reaction of the free alcohol on
- Glycerol carbonate is made with anhydride groups of a polymer.
- polymers with anhydride groups are generally not during the reaction

- the polycondensation takes place at temperatures between 150 and 280 ° C within 3 to 30 hours. In this case, a large part of the released amount of water is first distilled off at atmospheric pressure. In the course of the remaining reaction water and volatile diols is split off until the desired molecular weight is reached. Optionally, this can be facilitated by reduced pressure, enlargement of the surface or by passing an inert gas stream.
