Abstract:
1. A fluidized bed reactor having a reactor wall coating, wherein said reactor wall coating is formed in situ on a reactor wall during polymerization of olefin monomer, said reactor wall coating having a thickness of at least 100 μm and a molecular weight distribution comprising a major peak having: (a) an Mw/Mn ratio of less than 10; (b) an Mz/Mw ratio of less than 7, and (c) a maximum value of d(wt %)/d(log MW) at less than 25,000 daltons in a plot of d(wt %)/d(log MW), where MW is the molecular weight in daltons, wherein said wall coating is formed in situ on a reactor wall during polymerization of olefin monomer in the presence of bimetallic catalyst and an aluminum alkyl cocatalyst to form a reactor wall coating on the interior reactor wall.
