A substantially linear polyethylene made with a single-site-type catalyst in a CSTR

 

A substantially linear polyethylene made with a single-site-type catalyst in a CSTR operated at steady state has Mw= 150,000 and = 2.7. a) Plot the MWD of the whole polymer. b) Calculate the LCB frequency per 1000 carbon atoms for this substantially linear polyethylene. c) What are the mass fractions of the populations with 0 (linear) to 10 LCBS per d) Plot the MWD of the populations with 0 (linear) to 10 LCBs per chain. e) Calculate the frequency of LCB formation, knowing that at the polymerization conditions this polyethylene is made, the following data is available: Frequency of transfer to monomer Frequency of transfer to cocatalyst Frequency of transfer to hydrogen Frequency of beta-hydride elimination Frequency of propagation KTM [M] = 0.1 S-1 KtAl [Al] = 0.001 S-1 KtH [H] = 0 ktg = 0.1 s-1 kp[M] = 1000 S- chain?
