Here we report the modelling of thermally initiated RAFT step-growth polymerization kinetics of maleimide and acrylate monomers with bifunctional RAFT agents bearing tertiary carboxyalkyl-stabilized fragmentable R groups. By analytically solving the governing equations of our model, derived from the proposed mechanism, we demonstrate that the kinetics of these polymerizations follows first order with respect to monomer concentration. Furthermore, the obtained apparent rate constant (k_app) values indicate that acrylate monomers polymerize at slower rates compared to maleimide monomers during thermally initiated RAFT step-growth polymerization.

热引发 RAFT 阶梯生长聚合的机理和建模


在这里，我们报告了马来酰亚胺和丙烯酸酯单体的热引发 RAFT 阶梯生长聚合动力学的建模，其中双功能 RAFT 试剂带有叔羧烷基稳定的可碎裂 R 基团。通过解析求解从所提出的机制得出的模型的控制方程，我们证明了这些聚合的动力学在单体浓度方面遵循一阶。此外，获得的表观速率常数 （k_app） 值表明，在热引发 RAFT 阶梯生长聚合过程中，与马来酰亚胺单体相比，丙烯酸酯单体的聚合速率较慢。
