Polyethene

Polyethene is a very basic plastic, a simple polymer.

Before polymerization, it is built up of Ethene molecules:

    H   H
    |   | 
    C = C
    |   |
    H   H

The angles are soewaht different than shown in ASCII.

(CH2 = CH2) (Two CH2 connected by a double bond?)

In the polymerization process, the [double bonding]? is split up and a macromolecule? is thus created.

    H   H   H
    |   |   |
R - C - C - C - R
    |   |   |
    H   H   H

(R-CH2-CH2-CH2-R)

R indicates that the chain consisting of the same Compound CH2 continues.
