Question

The Ziegler-Natta catalyst used for polymerisation of ethene and styrene is $TiC{l}_4+(C_2{H}_5{)}_{3}Al$, the catalysing species (active species) involved in the polymerisation is :

• A. $TiC{l}_4$
• B. $TiC{l}_3$
• C. $TiC{l}_2$
• D. $TiCl$

Answer 1

The correct option is B $TiC{l}_3$

catalysing species (active species) involved in the polymerisation is $TiC{l}_3$ as
