摘要：
In this work a comprehensive mathematical model of the nitroxide mediated polymerization in tubular reactors is developed. The model is able to predict average molecular properties, such as the average molecular weights and copolymer composition. Besides, detailed calculation of the copolymer microstructure is included. The model is able to predict the bidimensional molecular weight distribution of the copolymer, the sequence length distribution, the global molecular weight distribution and the copolymer composition distribution. In particular, styrene-alpha methyl styrene and styrene-methyl methacrylate copolymerizations are studied. Model outputs are consistent with known features of the system. The detailed information on the copolymer molecular structure provided by the model makes it a valuable tool for the process design.
