Question

What is polyethene? Is it a hydrocarbon?How is the bond formation?

Answer 1

Polyethylene or polythene is the most common plastic
What is the monomer of polyethylene?
ethylene
Here ethylene (ethene) is the monomer, and the corresponding linear polymer is called high-density polyethylene (HDPE).


Monomers can join together to form polymers. Addition polymers are formed from alkenes. For example: ethene can polymerise to form polyethene, which is also called polythene.

Some small molecules can join together to make very long molecules called polymers. This process is called polymerisation. Many polymers are made from chemicals that are obtained from crude oil. For example, molecules of ethene join together to make poly(ethene), commonly known as polythene.

The formation of polyethylene from ethylene (ethene) may be illustrated in the graphic on the left as follows: The electrons in the double bond are used to bond two monomer molecules together. ... Note that in the complete polymer, all of the double bonds have been turned into single bonds.

Polyethylene consists of nonpolar, saturated, high molecular weight hydrocarbons. Therefore, its chemical behavior is similar to paraffin. The individual macromolecules are not covalently linked. Because of their symmetric molecular structure, they tend to crystallize; overall polyethylene is partially crystalline. Higher crystallinity increases density and mechanical and chemical stability.
