摘要：
The Monte Carlo simulation method proposed in Part 1 of this series is used to investigate the branched architecture of hyperbranched polymers formed through self- condensing vinyl polymerization (SCVP) in a continuous stirred- tank reactor (CSTR). The degree of branching (DB) at large chain length (P) limit, DBinf, does not change with the mean residence time t. The value of DBinf is larger than the corresponding batch polymerization. The relationship between the mean- square radius of gyration < s2> 0 and P does not change with t, and high molecular weight (MW) polymers obtained in a CSTR are much more compact than those formed in batch polymerization. At least for the high MW polymers, CSTR is advantageous to synthesize compact hyperbranched polymers.
