Mathematical Study on the effect of interval time of catalyst addition in long chain branched polymerization with binary catalyst system

Long chain branched polymerization of polypropylene is simulated with method of moments in a semi-batch reactor. Effect of interval time of catalyst addition between two catalysts as a process parameter is studied. It’s shown for longer and more branches, more interval time is required. Also for higher molecular weight, more interval time is better. But for more similar polymer chains (low PDI), high interval time is not suitable. For more similar branches high interval time is better
