摘要 For the -type polymerization, the gel fractional conversion is split into the tree-gel and the loop-gel fractional conversions, and it is the latter two conversions’ behavior that is studied in the post-gel regime. These two conversions are shown to be useful in studying the property of the network from gel point to end point in the process of post-gel polymerization. Furthermore, the influence of the stoichiometric ratio on the tree-gel and the loop-gel conversions is discussed. For the A a 1 ... A a s \_B b 1 ...
