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.
