Synthetic polymers are most commonly derived from oil, coal or natural gas. Many homes are clad and painted with polymers. Polymers are finding a dominant role in structural and decorative materials for land, sea and air transportation vehicles.
Most consumer products contain polymers and are packaged in polymers.
In addition, it is to be noted that most common polymers are easily recyclable. Polymer science is evident wherever one looks in our society today, but this field is still young and has a great deal more to offer.
