Question

High density polyethylene (HDPE) can be prepared from ethylene by:
A.Ziegler-Natta process.
B.Heating with peroxides.
C.Condensing in sealed tubes.
D.Condensing with styrene.

Answer 1

We have to know that high density polyethylene (HDPE) is a hydrocarbon polymer arranged from ethylene or oil by a reactant cycle. It is a sort of thermoplastic, which is renowned for its rigidity. Its interesting properties can stand high temperatures.

Complete answer:
We have to know that, for the most part, in the polymerization interaction, these impetuses structure free revolutionaries toward the finish of the developing polyethylene particles. They likewise add new ethylene monomers toward the finish of the atoms subsequently framing a long straight chain.
High density polyethylene (HDPE) for the most part includes a low level of stretching where the direct particles or the polymer chains are pressed together firmly. The presence of a solid intermolecular power brings about a thick, exceptionally translucent material. Nonetheless, the genuine component of the blend of high-thickness polyethylene is as yet a discussed subject.
We have to know that high density polyethylene is a hydrocarbon polymer that can be set up from ethylene by means of a synergist cycle. Some basic impetuses utilized here incorporate Ziegler–Natta impetuses, chromium or silica impetuses (Phillips impetus), and metallocene impetuses.

Hence, the correct option is (A) Ziegler–Natta process.

Note:
We have to see some uses of high density polyethylene. Jug covers and jugs are made of this polymer. It is additionally utilized in $3 - D$ printing fibers. High density polyethylene is utilized in the gas tanks of a few sorts of cars. It is utilized in plastic timber and wood plastic composites.
