摘要

可控聚合技术，如可逆加成裂解链转移聚合(RAFT)，对氧等杂质很敏感。这项工作探讨了应用再引发作为一种工具，以提高单体转化。建立了氧抑制RAFT分散聚合合成聚(4-乙烯基吡啶)-b-聚苯乙烯(P4VP-b-PS)的动力学模型。因此，使用动力学模型，可以部分预测被抑制的RAFT聚合的重新引发(单体转化率≤10%)。通过再引发作为溶液，合成了转化率高(>96%)、分散性好(≤1.2)的P4VP-b-PS共聚物。

Experimental & Modelling Digital Twin Approach for Polymer Synthesis via Re-initiated Oxygen inhibited RAFT Polymerization

Controlled polymerization techniques like the reversible-addition fragmentation chain transfer polymerization (RAFT) are sensitive to impurities such as oxygen. This work explores the application of re-initiation as a tool to enhance monomer conversion. A kinetic model for the oxygen inhibited RAFT dispersion polymerization for the synthesis of poly(4-vinylpyridine)-b-polystyrene (P4VP-b-PS) is developed. Thus, using the kinetic model, the re-initiation of the inhibited RAFT polymerization is partially (monomer conversion ≤10%) predicted. By implementing the re-initiation as a solution, the synthesis of P4VP-b-PS copolymers with the high conversion (>96%) and a good dispersity (≤1.2) is enabled.
