PRELUDIUM 21

Project entitled “Modeling the structure of glycerol polyesters depending on the process parameters” consists of creating mathematical models which could propose the conditions for obtaining polyesters with a specific structure and thus with specific properties. In the project, polyester resin from glycerol and dicarboxylic acids will be synthesized. Then the resins will be thermoset to solid films without defects, which will allow for reliable testing of their properties. Glycerine is a triol, which has three reactive hydroxyl groups. There are two primary groups with higher reactivity and one secondary group with lower reactivity. Due to the trifunctional nature of glycerine, the formation of branched structures is possible. However, the different reactivity of the hydroxyl groups can be used to control branch formation. Branching significantly affects the properties of resins and films. It is now known that by changing the parameters of the production process of glycerol polyesters, their properties, such as glass transition temperature, elastic modulus, tensile strength, or even viscosity, change significantly. Unfortunately, so far, no one has investigated how the preparation methods affect the structure of polyesters of glycerol, from which their properties are directly derived.
