Based on an analysis of experimental results and published data, the main elementary steps of the anionic coordination polymerization of butadiene rubber on a cobalt-containing catalyst in the presence of ethylene were found, and a mathematical model of the periodic process at an optimum water content was developed. The molecular-weight characteristics of the process depending on ethylene concentration were studied with the use of this model. 相似文献

The synthesis of butadiene rubber mediated by a lanthanide catalyst system based on neodymium(III) chloride in a batch reactor was mathematically modeled. The mechanism of the process was identified and the rate constants of various reaction steps were determined. It was found that chain transfer reactions with different rate constants have an effect on the molecular-mass characteristics of butadiene rubber. 相似文献

The synthesis of butadiene rubber on cobalt- and neodymium-containing catalytic systems in a reactor cascade has been simulated taking into account heat removal through the reactor jackets. The problem of optimization of the operating regime has been solved for butadiene polymerization in a cascade of continuous reactors. The regions of initial process parameters admissible for obtaining a high-quality rubber have been determined. 相似文献

Based on experimental results and reference data, the main elementary stages of butadiene polymerization on a cobalt-containing catalyst were determined and a mathematical model of the polymerization was developed. The following characteristics of the process were studied using this model: number-average, weight-average, and sedimentation-average degrees of polymerization and branching factor. 相似文献
