Abstract |
An improved process for the preparation of high molecular
67 Abstract weight narrow molecular weight distribution non crystalline
hydrocarbon soluble po f dC olefins which comprises of
a heating a novel homogeneous Mg complex catalyst prepared
by the process as here in described with an organoaluminura
compound of the formula AIR X 3 n where R is a hydrocarbon
radical contain 1 2 0 carbon atoms X is a halogen atom
and n « 2 Or 3 as a cocatalyst in the presebce if an organic
solvent at a teraperatufe in the range of 40 80Q c
b cooling the reaction mbdure to a temperature in the range
of 0 6OoC.
c adding £ olefin having at least 4C atom to the cooled
catalyst maintaining the tejaperature between 0.60° C under
vigorous agitation and
dj terminating the reaction by the addition of a acidified
roathanol andjseparat.ing. a .£££ Aj L tated polyraer by filtration |
