Ziegler-Natta Catalyst is used in the manufacture of
Polyacrylonitrile
Terylene
High density polythene
Low density polythene
The correct option is: (C) High density polythene.
The Ziegler-Natta Catalyst is indeed used in the manufacture of various types of polyethylene, which includes HDPE, LDPE, and LLDPE. Polyethylene is a versatile polymer with a wide range of applications, and the Ziegler-Natta Catalyst allows for the controlled polymerization of ethylene monomers to produce different types of polyethylene with varying properties.

If cosθ = \(\frac{-3}{5}\)- and π < θ < \(\frac{3π}{2}\), then tan \(\frac{ θ}{2}\) + sin \(\frac{ θ}{2}\)+ 2cos \(\frac{ θ}{2}\) =
Three long, straight, parallel wires carrying different currents are arranged as shown in the diagram. In the given arrangement, let the net force per unit length on the wire C be F. If the wire B is removed without disturbing the other two wires, then the force per unit length on wire A is:
The alkali metal with the lowest E M- M+ (V) is X and the alkali metal with highest E M- M+ is Y. Then X and Y are respectively:
The number of significant figures in the measurement of a length 0.079000 m is:
The roots of the equation x4 + x3 - 4x2 + x + 1 = 0 are diminished by h so that the transformed equation does not contain x2 term. If the values of such h are α and β, then 12(α - β)2 =
