Question

Zeigler-Natta catalysts:

• A. are triethyl aluminium titanium tetrachloride complex $(C_2{H}_5{)}_{3}Al+TiC{l}_4$
• B. are used to prepare stereospecific addition polymers
• C. are employed to have stereochemical contol of the polymerisation process
• D. All of the above

Answer 1

The correct option is A are triethyl aluminium titanium tetrachloride complex $(C_2{H}_5{)}_{3}Al+TiC{l}_4$

Ziegler-Natta heterogeneous supported catalysts based on titanium compounds are used in polymerization reactions in combination with cocatalysts, organoaluminum compounds such as triethylaluminium ($Al(C_2{H}_5{)}_3$).
