Abstract
We created polyester, which building blocks naturally occur in the human organism: glycerol and succinic acid. A process of preparation of poly(glycerol succinate) resins and its purification was developed. The resins were obtained in a polycondensation reaction with the monomer being prepared in situ. Due to that, succinic anhydride and glycerol were used as reaction substrates. The obtained resins were next crosslinked toelastomers. Mathematical models described both processes for the first time in the case of poly(glycerol succinate). Such models are allowing for defining the process parameters to obtain a material with desired properties. For example, optimal conditions for resins synthesis were estimated, and requirements for yielding elastomer with Tg in range −10 to 40°C could be determined based on our second model. Such a novel approach combines science with industry needs, where knowledge of processes is key to success. Also, it has to be said that glycerol, which is a waste of biodiesel production, could be used in our process, but we recommend prior purification.
