ABSTRACT:
Recent successful examples for synthesis of new polyolefins containing (polar)
functionalities by adopting the approaches by controlled incorporation of
reactive functionalities (and the subsequent introduction of polar functionalities
under mild conditions) by coordination polymerization in the presence of
transition metal complex catalysts have been described. Related methods (such
as direct copolymerization of olefin with polar monomer using living radical or
coordination insertion methods) have also been demonstrated for comparison. Our
recent efforts for precise synthesis of polyolefins containing polar
functionalities by efficient incorporation of reactive functionality by
copolymerization of ethylene with nonconjugateddiene (1,7-octadiene, vinylcyclohexene
etc.) or divinyl-biphenyl using nonbridged half-titanocene [ex. Cp’TiCl2(O-2,6-iPr2C6H3),
Cp’ = C5Me5, tBuC5H4 etc.] catalysts have been introduced.
