中文摘要：

利用Monte Carlo模拟方法研究了由单体、引发单体和引发核组成的三元自缩合乙烯基聚合反应体系．重点考察了两类活性基团反应活性的差异、引发单体分数、引发核的配比及活性基团数等因素对体系中无核和有核两类超支化高分子z均回转半径的影响．结果表明，这些因素对超支化高分子的结构和尺度影响显著，因而通过调节有关参数可以实现对超支化高分子结构和尺度的调控．

英文摘要：

The Z-average radius of gyration of hyperbranched polymers torrned m tlae ternary selI-conaensmg vinyl polymerization system was studied by the method of Monte Carlo simulation, in which the unequal reac- tivity was taken into account. As a result, the effects of the reactivity difference in two types of active centers, the molar ratio of inimers to monomers, the molar ratio and functionality of core initiators were discussed. It is found that these factors can give rise to a significant influence on the Z-average radii of gyration of hyperbranched polymers with and without the core initiator. This provides some useful clues for regulating the dimension and structure of the hyperbranched polymers in the relevant experiments.
