Question
nCH2=CH2→[−CH2−CH2−]n
In the above reaction, catalyst is :
In the above reaction, catalyst is :
Open in App
Solution
The correct option is B Ziegler-Natta
Ziegler-Natta catalysts are mixtures of
titanium compounds like titanium(III) chloride, TiCl3, or titanium(IV)
chloride, TiCl4, and compounds of aluminium like aluminium triethyl, Al(C2H5)3.
There are all sorts of other catalysts constantly being developed.
These catalysts are used to make low density poly(ethene). The chains grow in
a much more controlled - much less random - way.
