Formulation of Pseudo-distribution Problem

CLD/DBD for Mixed-metallocene Polymerization of Ethylene 9.6.2.1 Formulation of Pseudo-distribution Problem 

1 ) Catalyst activation and initiation are taken as one step. P l Note that P , = + P -. 

In fact, 0 and T represent the moments of the branching distributions of living and dead chains at the given chain length, n. Thus, the branching polydispersity D follows from the second branching moment according to  

In order to derive the balance equations for the branching moment distributions, the following steps have to be performed [31)  

All equations are solved simultaneously. This procedure can in principle be applied to any polyreaction model where additional properties have to be considered. The key is how a certain reaction step changes the additional property.
