MMD of Polydisperse Linear Polymers from Rheological Data

More about the book

Focusing on the inversion of transfer coefficient functionals in dense polymeric liquids, this work introduces a regularization method using a heuristic rheological model. By emphasizing inverse time dependence and neglecting thermodynamic properties, it enables the calculation of molecular mass distribution for simple liquids like polyethylene and polypropylene melts. The method proves effective in quality assessment during polymer melt extrusion and in studying degradation processes, offering insights without requiring prior information about the system.
