Fund Project: Financial support of this research from the National Natural Science Foundation of China is gratefully acknowleged.

Transformation of living ring-opening metathesis polymerization (ROMP) into coordination polymerization by converting the titanacyclobutane attached to a polynorbornene (polyNBE) chain into titanocene alkoxide has been used to the synthesis of poly(NBE-b-ethylene).The copolymerization product,after being extracted by CH₂Cl₂ to separate the NBE homopolymer,exhibits the Tg of polyNBE segments and Tm of polyethylene segments by DSC measurement.
