中文摘要	neutral ni(ii) salicylaldiminato complexes activated with modified methylaluminoxane as catalysts were used for the vinylic polymerization of norbornene. catalyst activities of up to 7.08 x 10(4) kg(pol)/(mol(ni) (.) h) and viscosity-average molecular weights of polymer up to 1.5 x 10(6) g/mol were observed at optimum conditions. polynorbornenes are amorphous, soluble in organic solvents, highly stable, and show glass-transition temperatures around 390 degreesc. catalyst activity, polymer yield, and polymer molecular weight can be controlled over a wide range by the variation of the reaction parameters such as the al/ni ratio, monomer/catalyst ratio, monomer concentration, polymerization reaction temperature, and time.
