Figure 9 Mass distribution of polybutadiene comparing all cases.
The pressure profiles for all cases were very similar with practically overlapping points. It can be noted that there were pressure peaks at the beginning of the process in the reactor, reaching values between 3.0 and 3.3 bar. However, the pressure stabilized as the reaction proceeded until the initial pressure of 2 bar was reached. It was also possible to see that the pressure profile considering 2 active sites had the highest peak pressure and that the profile considering 4 sites obtained the lowest peak pressure as can be seen in the Figure 10.
