Reactor wall coating and processes |
摘要 |
Reactor wall coatings for polymerization reactors and processes for forming such coatings are disclosed. The reactor wall coatings can have a thickness of at least 100 mum and a molecular weight distribution including a major peak having one or more of an Mw/Mn ratio of less than 10; an Mz/Mw ratio of less than 7; and 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. The reactor wall coatings can be formed in-situ during polymerization, on reactor walls initially free of a reactor wall coating, or having a pre-existing reactor wall coating.
