For the two first fragmentation steps, HALP and LALP systems behave similarly.
B] as a function of r/R) at different times during the first two fragmentation steps of the LALP system are shown in Fig.
The resulting monomer concentration profiles in the accessible pore volume of the particle at the end of each fragmentation step for the LALP system are displayed in Fig.
When a high activity catalyst under laboratory conditions (or HALP system) is modeled, the predictions are similar to those found for the LALP system in Figs.
In general, no appreciable changes in the concentration levels in the LALP and HALP systems are observed.
Figure 13 shows porosity changes for long polymerization times in both LALP and HALP systems, confirming the trend observed in Fig.
In this work, only two experiences were simulated, one for each LALP and HALP systems.
As was detailed in Part I for LALP and HALP systems, porosity remains almost constant for the remainder of the polymerization process.
LALP and HALP systems show an almost linear increase in yield with time after fragmentation.
