Plastics can be made in a variety of ways from a variety of materials shale gas, oil, plants even chicken feathers can all be used to make plastic however oil derived plastics are the most common plastics are created from single units combined in a variety of ways this process is called. The manufactured or synthetic plastics are often designed to mimic the properties of natural materials plastics, also called polymers, are produced by the conversion of natural products or by the synthesis from primary chemicals generally coming from oil, natural gas, or coal.
Plastic bottles, films, cups, and fibers are thermoplastic plastics polymers abound in nature the ultimate natural polymers are the deoxyribonucleic acid (dna) and ribonucleic acid (rna) that define life.

The first synthetic manufactured plastic was bakelite, created in 1909 for telephone casing and electrical components the first manufactured polymeric fiber was rayon, from cellulose, in 1910 nylon was invented in 1935 while pursuing a synthetic spider silk. Synthetic polymers are human-made polymers from the utility point of view they can be classified into four main categories: thermoplastics , thermosets , elastomers and synthetic fibers they are found commonly in a variety of consumer products such as money, glue, etc. What are synthetic plastics plastic molecules are made of long chains of repeating units called monomers the atoms that make up a plastic’s monomers and the arrangement of the monomers within the molecule both determine many of the plastic’s properties.
Synthetic polymers, which includes the large group known as plastics, came into prominence in the early twentieth century chemists' ability to engineer them to yield a desired set of properties (strength, stiffness, density, heat resistance, electrical conductivity) has greatly expanded the many roles they play in the modern industrial economy. Plastics are one of the classification of polymers if a polymer is shaped into hard and tough utility articles by the application of heat and pressure ,it is used as “plastic” synthetic polymers are often referred to as plastics, such as the well-known polyethylene and nylon.
The seven most common types of synthetic organic polymers are: low density polyethylene (ldpe), high density polyethylene (hdpe), polypropylene (pp), polyvinyl chloride (pvc), polystyrene (ps), nylon, teflon, and thermoplastic polyurethane (tpu.
