Constitutive modelling of dispersive polymer blends

Several different types of polymers can be combined to make materials with specifically tailored properties. An important category of polymer blends consists of the immiscible polymer blends. This means that the different constituents remain separate distinctive phases within the material. In the case of dispersive blends, one polymer exists as droplets dispersed within a matrix phase of the other polymer. The properties of such materials depend strongly on the size, shape and orientation of these droplets.

The goal of this project is to develop a constitutive model to describe the evolution of the droplet structure in processing conditions. The model is to be validated using experimental data from the industrial partner Sabic.

Type of research: Numerical/modelling
