Synthetic macromolecules


Synthetic Polymers

Synthetic macromolecules are polymers, which are the basis for the manufacture of plastics.

Plastics began production in the late nineteenth century and are of great importance in the development of the twentieth century.

From these macromolecules, it was possible to obtain, in addition to plastics, textile fibers, such as nylon and polyester, and synthetic rubbers.

Polymers are made up of very large molecules that are formed by repeating a small molecular unit called monomer.

Examples:

     
Examples of synthetic polymers: plastic cup, PET bottles and synthetic rubber tire.

Addition polymers are those where the polymer is the sum of small molecules all equal to one another.

Examples of addition polymers are polyethylene, polypropylene, vinyl chloride, polystyrene, vinyl polyacetate, teflon, methyl polymethacrylate and polyacrylonitrile.

We will study each of them below.
