THE ACTIVITY OF RARE EARTH CATALYST SYSTEM Na(naph)3-AlEt2Cl-Al(i-Bu)3 IN DIENE POLYMERIZATION
The chemical composition of reaction products of a rare earth catalyst
Na(naph)3
AlEt3Cl and Al (i-Bu)3
has been analyzed
and its activity in polymerization of isoprene was studied using kinetic method. The results revealed that the recipe of catalyst components and the method of preparation effected the activity markedly. Besides
the utilization coefficient of the catalyst increased with decrease in catalyst concentration and attained constant value. It was found that the active sites was occupied by excess AlEt2Cl present in the system and thus led to the chain termination reaction.
