Abstract
[(η 5 -C 5 Me 4 )SiMe 2 (NtertBu)]TiCl 2 was used as catalyst in the presence of methylaluminoxane (MAO) for the copolymerisation of ethylene with 5,7-dimethylocta-1,6-diene (5,7-DMO) and with 3,7-dimethylocta-1,6- diene (3,7-DMO), two linear non-conjugated dienes readily available from terpene feedstock. The effects of reaction temperature, Al/Ti mole ratio and diene concentration in feed on the polymerisation activity and on the incorporation rates of the diene were investigated. The structure of the polymer and the distribution of the comonomer along the chains were investigated through NMR and DSC.
