The structure of a polymer can be drawn given either the structure of the monomer or the repeating unit. From the structure of a polymer, the monomer or repeating unit can be drawn. Addition ...

In an ethene molecule, CH 2 =CH 2, the two pairs of electrons which make up the double bond aren't the same. One pair is held securely on the line between the two carbon nuclei in a bond called a sigma bond. The other pair is more loosely held in an orbital above and below the plane of the molecule known as a π bond.

The cast sheet is used in baths and other sanitary ware, which along with illuminated signs, is the largest use of the polymer.
Weba small amount of oxygen as an impurity. It is unlikely that you will need to know these conditions. I include them just out of interest and to show that it would be difficult to do this in a school lab! Half of each double bond is broken, and the electrons are used to join on … But in the lab, we normally avoid using dangerous liquid bromine and instead … This is exactly like the polyester repeat unit and chain except that the single-bonded …
