| Abstract: | For the A a 1 ... A a s \_B b 1 ... B b t 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. |
