摘要: This article shows how the method of instantaneous distributions can be used to model microstructures polymers made under different polymerization conditions. The three main investigated are chain length (CLD), chemical or comonomer composition (CCD), and long branching (LCBD). It is also explained combined with reactor models calculate cumulative distribution in reactors having residence time distributions, spatial gradients. Finally, usefulness this mathematical modeling technique illustrated several case studies involving olefin polymerization. Extensions for free-radical covered appendices.
