Title:
2個以上のヘテロ原子を含有する架橋された二環式および多環式のオレフィンの開環メタセシス重合
Document Type and Number:
Japanese Patent JP4295096
Kind Code:
B2
Abstract:
A method is provided for synthesizing a polymer in a controlled fashion using a ring-opening metathesis polymerization (ROMP) reaction, wherein polymerization is carried out using a catalytically effective amount of an olefin metathesis catalyst and a bridged bicyclic or polycyclic olefin monomer that contains at least two heteroatoms directly or indirectly linked to each other. Preferred catalysts are Group 8 transition metal complexes, particularly complexes of Ru and Os. Such complexes include the ruthenium bisphosphine complex (Pcy 3 ) 2 (Cl)2Ru=CHPh (1) and the ruthenium carbene complex (ImesH 2 )(Pcy 3 )(Cl) 2 Ru=CHPh (2). The invention also provides novel regioregular polymers synthesized using the aforementioned methodology, wherein the polymers may be saturated, unsaturated, protected, and/or telechelic. An examplary polymer is poly((vinyl alcohol) 2 - alt- methylene)(MVOII).
