How are organic polymers made?
Organic polymers are macromolecules composed of many repeating monomer units. These polymers are synthesized by enzyme-mediated processes in cells. In general, synthetic polymers are derived from monomers that contain either a multiple bond, or two or more functional groups, or a three- to seven- membered ring.
What is organic polymers?
Organic polymers are linear, branched, or cross linked, and they give rise to different types of synthetic materials, such as amorphous or semicrystalline thermoplastics, elastomers, and high-strength fibers, which are essential to many modern technologies.
How do you make polymers?
Monomers join together to make polymer chains by forming covalent bonds—that is, by sharing electrons. Other bonds then hold the groups of chains together to form a polymer material.
What are the four main organic polymers?
There are four basic kinds of biological macromolecules: carbohydrates, lipids, proteins, and nucleic acids. These polymers are composed of different monomers and serve different functions.
What are polymers examples?
Examples of synthetic polymers include nylon, polyethylene, polyester, Teflon, and epoxy. Natural polymers occur in nature and can be extracted. They are often water-based. Examples of naturally occurring polymers are silk, wool, DNA, cellulose and proteins.
Where can polymers be found?
Natural polymers include:Proteins, such as hair, nails, tortoiseshell.Cellulose in paper and trees.Starches in plants such as potatoes and maize.DNA.Pitch (also known as bitumen or tar)Wool (a protein made by animals)Silk (a protein made by insects)Natural rubber and lacquer (proteins from trees)27 Jun 2019
What is the revised classification of polymers?
The most common way of classifying polymers is to separate them into three groups - thermoplastics, thermosets, and elastomers. The thermoplastics can be divided into two types - those that are crystalline and those that are amorphous.
What are the three types of polymers?
There are 3 principal classes of polymers – thermoplastics, thermosets, and elastomers. Differentiation between these classes is best defined by their behaviour under applied heat. Thermoplastic polymers can be either amorphous or crystalline. They behave in a relatively ductile manner but often have low strength.
Are proteins a polymer?
Proteins are polymers in which the 20 natural amino acids are linked by amide bonds. Structural proteins can be globular or fibrillar proteins.
