Let's get this thread started again..! I have a question, anyone want to explain to me what the hell a Ziegler Natta catalyst is? The pre-lease doesn't make it very clear in my opinion

Question 1: what is the difference between heterogeneous and homogeneous catalysts?

Is that the only difference/what are others?
