Question

Ziegler – Natta catalysts are:

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

Answer 1

The correct option is D All the above

Ziegler Natta catalyst is a mixture of triethylaluminium $(C_2{H}_5{)}_{3}Al$ and titanium tetrachloride $\left(TiC{l}_4\right)$. It is used to produce High density polythene (HDP).
Ziegler Natta catalyst remain dominant in production Technology for polyolefins due to significant cost benefits and low cost of polymers .
