Study Notes
Polymer Basics
- A polymer is a macromolecule composed of many smaller molecules, called monomers, that are bonded together.
- The term "polymer" comes from the Greek words "poly" meaning many and "meros" meaning part.
Physical Properties of Polymers
- Thermal expansion refers to the extent to which a polymer expands or contracts when heated or cooled.
- Thermal insulation refers to the extent to which a plastic or polymer acts as an effective insulator against the flow of heat.
- Tensile strength refers to the force it takes to stretch the plastic in one direction.
- Permeability refers to the extent to which a polymer can pass extraneous materials.
- Transparency refers to the extent to which a plastic affects light as it passes through the polymer.
Types of Polymers
- Natural polymers are materials that widely occur in nature or are extracted from plants or animals.
- Examples of natural polymers include cellulose, proteins, and starch.
- Synthetic polymers are man-made materials that are created in a laboratory or factory.
- Examples of synthetic polymers include nylon, polyester, and polyethylene.
Examples of Polymers
- Hemoglobin is a natural polymer responsible for carrying oxygen from the lungs to the body's tissues.
- Cellulose is a natural polymer that provides structural support to plants and is an important source of dietary fiber for humans.
- Proteins are natural polymers that constitute almost all living organisms and include enzymes.
- Collagen is the most abundant protein in the human body and provides structure and support to skin, bones, tendons, and other connective tissues.
- Nylon is a synthetic polymer often referred to as a type of plastic.
Polymer Structure
- In crystalline polymers, the polymer chains are arranged in a regular structure instead of a random fashion.
