Plastic initially received its critics primarily because it was so common and, at the time the first plastics were invented, associated strongly with Tokyo during WWII. After the war cured, manufacturers rapidly introduced their new product that had been developed as an alternative to glass and cutlery. Plastic quickly became a must in our lives for packaging all types of items especially food items. It is also used extensively for medical supplies (dental and medical equipment) as well as toys.This is an article on when was plastic invented. We cannot watch it unless you join us.

What happens when monomers are chemically bonded into chains?
This happens when monomers are chemically bonded into chains. There are two different mechanisms for polymerisation: Addition polymerisation. The addition polymerisation reaction is when one monomer connects to the next one (dimer) and dimer to the next one (trimer) and so on.
What is the reaction of adding monomers?
The addition polymerisation reaction is when one monomer connects to the next one (dimer) and dimer to the next one (trimer) and so on. This is achieved by introducing a catalyst, typically a peroxide. This process is known as chain growth polymers – as it adds one monomer unit at a time.
Why is plastic synthetic?
The vast majority of plastic in use today is synthetic because of the ease of manufacturing methods involved in the processing of crude oil.
What is the difference between polymer and plastic?
plastic. All plastics are essentially polymers, but not all the polymers are plastics. The term polymer and monomer are derived from Greek words: where ‘poly’ means ‘many’, ‘mer’ means ‘repeating unit’ and the word ‘mono’ means ‘one’.
How is oil extracted?
Extraction of oil – Oil is pumped from underground to the surface where tankers are used to transport the oil to the shore. Oil drilling can also take place under the ocean using support from platforms. Different size pumps can produce between 5 – 40 litres of oil per stroke (Figure 1).
How are polymers formed?
Polymers are larger molecules formed by covalently joining many monomer-units together in the form of chains like pearls on a string of pearls. The word plastic comes from ‘plasticus’ (Latin for ‘capable of moulding’) and ‘plastikos’ (Greek for ‘fit for moulding’).
How much of Europe’s oil and gas is used for plastic?
In Europe, only a small proportion (about 4 – 6%) of our oil and gas reserves goes towards the production of plastics, with the rest used for transport, electricity, heating and other applications ( Ref) Most of the plastic in use today is derived by the following steps: 1.
