Abstract
A novel composition is provided which is suitable for use as a catalytic support which contains chlorine, bromine and magnesium. The molar ratio of bromine to chlorine is critical and ranges between about 1:99 to about 50:50, preferably between about 2.5:97.5 to about 20:80, and most preferably between about 2.5:97.5 to about 15:85. The molar ratio of magnesium to combined chlorine and bromine is not critical but generally ranges between about 1:1.6 and about 1:2.0, preferably between about 1:1.8 and about 1:2.0. The composition is obtained by reacting an organo magnesium compound with a mixture of chlorinated and brominated aluminum compounds.
