The reactions of Solvay TiCl3-AlR3 (R=C2H5

i-C4H9) catalysts with acetyl chloride were studied. The main reaction

which is much faster than the reactions between A1R3 and CH3COC1

is as follows:It is found that when CH3COC1 was introduced into 1-octene polymerization systems catalyzed by TiCl3-AlR3 for 5-15min

it reacted selectively and completely with the active centers to produce acetyl-ended polymer chains.With CH3COC1 as a quenching agent

the number of active centers in .these polymerization systems were determined by measuring the content of carbonyl in the polymer

and the results consist with those obtained by kinetics-molecular-weight method.
