Living Insertion/Cyclization/Ring-Opening Polymerization: A Strategy for the Synthesis of Functional Propylene Copolymers and Block Copolymers

Detailed Technology Description: Polymerization of 1,5-hexadiene with a perfluorinated bis(phenoxyimine) catalyst system is reported

Others: None

*Abstract: Polymerization of 1,5-hexadiene with a perfluorinated bis(phenoxyimine) catalyst system is reported. The microstructure of the polymer contains the expected methylene-1,3-cyclopentane units as well as 3-vinyl tetramethylene units. A mechanism for formation of this polymer is proposed. This unusual reaction is also employed in the synthesis of monodispersed vinyl-functional polypropylene copolymers and block copolymers.
