Question

High density polythene __________ polymer of ethene.

Answer 1

Answer:

High density polythene High-density polyethylene polymer of ethene .

Answer 2

High-density polythene is an addition polymer of ethene made by polymerization:

• High-density polythene (HDP) is formed by the addition polymerization of ethene which is done using a hydrocarbon solvent.
• It is carried out in the presence of a catalyst like triethylaluminium and titanium tetrachloride also known as the Ziegler- Natta catalyst.
• The temperature needed for this reaction is in a range of 333-343 K with a pressure of 6-7 atm.
• The high density is a result of the close packing of the linear molecules.
• HDP is chemically inert and very hard.
• Uses of HDP: Buckets, dustbins, bottles, etc.
