What is a list of natural polymers?

Examples of naturally occurring polymers are silk, wool, DNA, cellulose and proteins. In our previous section on network polymers, we mentioned vulcanized rubber and pectin. Vulcanized rubber is a synthetic (man-made) polymer, while pectin is an example of a natural polymer.

What are 5 natural polymers?

The most important natural polymers are:

  • Cellulose.
  • Chiton.
  • Carbohydrates.
  • Proteins.
  • Nucleic acids.
  • Rubber.

What are some natural examples of polymers?

Natural polymers include silk, hair, proteins and DNA, while synthetic (man-made) polymers include polyethylene, polypropylene and polyester.

Is PVC a polymer?

Polyvinyl Chloride (PVC) is one of the most widely used polymers in the world. Due to its versatile nature, PVC is used extensively across a broad range of industrial, technical and everyday applications including widespread use in building, transport, packaging, electrical/electronic and healthcare applications.

Is Cotton natural polymer?

Cotton is a natural polymer. Chemical name of cotton is cellulose.

Is salt a polymer?

Salt is not a polymer. Common table salt is sodium chloride, which is an ionic complex.

Which is the best example of a natural polymer?

These polymers are formed as a result of condensation. 5) Rubber – Natural rubber is formed from the addition polymerization of isoprene monomers. It possesses elastic properties and hence is also called an elastomer. It is obtained from rubber latex secreted by rubber tree which is richly cultivated in the Kerala state of India.

Where are polymers found in plants and animals?

Polymers that are naturally obtained or extracted from nature (living organisms) are referred to as natural polymers. They are present abundantly in plants, animals and human beings. Natural polymers include proteins, DNA, RNA, starch, glycogen, etc.

How are polymers classified according to their properties?

Polymers are classified based on different properties and they include source, structure, mode of polymerization, molecular forces and growth polymerization. Derivatives of cellulose are semi-synthetic polymers.

Which is the correct description of degree of polymerization?

The number of monomers, or sometimes the number of repeat units, in a polymer is called the degree of polymerization. Polymers are often characterized as being thermoplastic or thermoset. A thermoplastic polymer will soften as it is heated (i.e., thermal treatment leads to plastic ow).
