A Kinetic and Heat Balance Model for Anionic Batch Block Copolymerization of Styrene and Isoprene
Von Wiley-VCH zur Verfügung gestellt
Anionic polymerization is an established method for the synthesis of block copolymers. The model presented and validated based on polymerizations enables a prediction of the temperature profiles and the molecular weight distributions, which makes it an ideal screening tool for the optimization of anionic polymerization in batch reactors.
Abstract
Anionic polymerization is an established process for the synthesis of well-defined block copolymers. Due to the high reaction rates, a good knowledge of the process and its heat generation is of great importance for safe reaction control. This is to be achieved by the development and validation of a combined kinetic and heat transport model. The validation of the combined model was based on the experimentally anionic homo-polymerization of styrene that was expanded for the block co-polymerization of styrene and isoprene carried out in cyclohexane in batch reactors.
