Product made from polymers are all around us: clothing made from synthetic fibers, polyethylene cups, fiberglass, nylon bearings, plastic bags, polymer-based paints, epoxy glue, polyurethane foam cushion, silicone heart valves, and teflon-coated cookware.
What Is Polymer Used For?
A polymer is a high molecular weight compound composed of repeating structural units. These units are typically connected by covalent bonds, and they may be connected by ionic, hydrogen, or other types of bonds.
Polymers are found in a wide variety of products, including plastics, rubbers, adhesives, and textiles. They are also found in biological systems, such as DNA and proteins.
The term “polymer“ is derived from the Greek word “poly,” meaning “many,” and “mer,” meaning “unit.” The first polymers were discovered in the early 19th century.
In 1828, German chemist Friedrich Wöhler synthesized a substance called urea, which is a compound of carbon, nitrogen, and hydrogen
. Wöhler‘s urea was the first synthetic organic compound, and it paved the way for the synthesis of other polymers. In the early 20th century, scientists began to study the properties of polymers and to develop methods for their synthesis.
In the 1930s, German chemist Hermann Staudinger demonstrated that polymers are long chains of small molecules, and he proposed that they are held together by covalent bonds. This discovery laid the foundation for the modern science of polymers
