摘要:
A novel catalyst for polymerization of olefin is provided which comprises a modified clay compound (a) having an average particle diameter of less than 10 .mu.m, a transition metal compound (b), and an organoaluminum compound (c). This catalyst exhibits improved initial polymerization behavior, and produces an olefin polymer of less ash content at a high productivity.
