The copolymerization of styrene and ethylene was attempted in the presence of the catalytic system CpTiCl,methylaluminoxane. Polymerizations were carried out at different polymerization temperatures and Al/Ti mole ratios. The structure of the polymer was investigated with FTIR, DSC, GPC, and "C-NMR
Copolymerization of styrene (St) and butadiene (Bd) with nickel(II) acetylacetonate [Ni(acac) 2 ]-methylaluminoxane (MAO) catalyst was investigated. Among the metal acetylacetonates [Mt(acac) x ] examined, Ni(acac) 2 showed a high activity for the copolymerization of St and Bd giving copolymers havi
