METHOD FOR PRODUCING NORBORNENE BASED ADDITION (CO)POLYMER

Title:

METHOD FOR PRODUCING NORBORNENE BASED ADDITION (CO)POLYMER

Document Type and Number:

WIPO Patent Application WO/2006/064814

Kind Code:

A1

Abstract:

A method for producing a norbornene addition polymer which comprises using C₅H₅NiCH₃(PPh₃) as a catalyst and B(C₆F₅)₃ as a cocatalyst; and a method for producing an addition copolymer of norbornene and methyl norbornene-carboxylate which comprises using C₅H₅NiCH₃(PPh₃) as a catalyst and B(C₆F₅)₃ as a cocatalyst. The above method allows the production of a norbornene based addition (co)polymer with good efficiency by using a specific catalyst system (a combination of a catalyst with a cocatalyst) exhibiting high polymerization activity.
