They are formed from the products (i.e alkenes and alkanes) of the fractional distillation of crude oil. Alkenes and alkanes are hydrocarbons - their molecules consist of hydrogen and carbon only.
Monomers of these substances bond to form long chains called polymers. Polymers are what make up plastics.
The vast majority of plastics are now made from monomers provided by the petroleum industry. These monomers are then polymerized to create the actual plastic, which is a polymer.
Building blocks
Most plastics come from hydrocarbon monomers - hydrogen and carbon. Occasionally another element, such as Fluorine, is added to make a different plastic. These monomer molecules are forced to join under heat and pressure (sometimes with a catalyst) to form a polymer. Another group use Silicon rather than carbon. These form the silicone plastics.
monosaccharides are the monomers of polysaccharides
well the answer is non other than Petroleum
Monomers
Either Hydrocarbons, monomers,plastics or polymers
Plastics are generally polymers made out of monomers such as ethene.
thermoplastic plastics (recyclable)thermosetting plastics (non-recyclable)
The correct question to ask would have been "Monomers that are found in proteins are called _______?" but to answer your question, Monomers that are in proteins are called amino acids.
As you stated, plastics are polymers, meaning they are made up of several smaller units called monomers. An example of this is a common material known as PVC. This stands for polyvinyl chloride, which is a polymer of vinyl chloride. Likewise, polysaccharides are also polymers, made up of smaller units, again called monomers. An example of this is a carbohydrate, which is made up of smaller sugars, such as glucose. So the difference between plastics and polysaccharides is that they are made up of different monomers. For plastics the monomer is an organic molecule, and for polysaccharides the monomer is a single saccharide, also known as a simple sugar.
Plastics contain polymeric (long chain molecules) which are built of repeating small units (monomers) an example is polyethylene (polythene) (C2H4)n

Either Hydrocarbons, monomers,plastics or polymers
When the links between the carbon atoms in the monomers becomes 2 and 3 dimensional the chains become much stronger. These plastics are known as Thermosets. Once these plastics are set they cannot be re moulded and shaped like thermoplastics can.
