Modeling of morphology evolution of high-impact polystyrene
Original language description
In the high-impact polystyrene (HIPS) production it is desirable that a two-level (the so-called salami) morphology develops: (i) irregular sub-micron polystyrene (PS) domains are dispersed in micron-sized polybutadiene (PB) particles, and (ii) oval PB particles of the size of several microns are dispersed in the continuum PS phase. We have used advanced tools of mathematical modeling as well as experimental methods to approach problems related to HIPS: (i) prediction of morphology-dependent impact resistance, (ii) characterization of HIPS morphology and thermodynamics of its components, and (iii) evolution of HIPS morphology. The morphology strongly affects the impact resistance and the gloss of the material. Mathematical model is centered about massbalances of species in the polymer/polymer/monomer system. The generalized gradient of chemical potential is considered as the driving force of diffusion transport instead of the usual concentration gradient employed in the simple Fick?s
