Which of the following are natural polymers

Natural polymers are those substances which are obtained naturally. These polymers are formed either by the process of addition polymerization or condensation polymerization. Polymers are extensively found in nature. Our body too is made up of many natural polymers like nucleic acids, proteins, etc.

How many natural polymers are there?

The three main groups of naturally-occurring polymers are polynucleotides, polyamides (or proteins) and polysaccharides.

What is the most common natural polymer?

What was the first natural polymer?

The first plastic material was based on nitrocellulose and was obtained by Parkes in 1862 and Hyatt in 1866. The addition of camphor to nitrocellulose led to the first thermoplastic (a modified natural polymer) known as celluloid.

Is cotton a natural polymer?

Cotton is made up of the natural polymer Cellulose which is made up of large monomers of Glucose.

Is wood a natural polymer?

In addition to these important to life polymers, natural polymers derived from plants and animals have been used by humans for many centuries. These include wood, cotton, leather, rubber, wool, and silk.

Is Bakelite a natural polymer?

Cellulose is a natural polymer made up of glucose. Bakelite, PVC and neoprene are synthetic polymers.

Is protein a natural polymer?

Proteins are one of many types of natural polymers, and they are the most versatile by far. You name it, proteins do it.

What are the 7 types of polymers?

What are the 3 main 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.

What are polymers give example?

polymer, any of a class of natural or synthetic substances composed of very large molecules, called macromolecules, that are multiples of simpler chemical units called monomers. Polymers make up many of the materials in living organisms, including, for example, proteins, cellulose, and nucleic acids.

Is oil a natural polymer?

Historically, fossil oils have been used as the main source of polymers; however, the use of plant oils for the production of polymers has been increasing each year. Using plant oils as a source for polymers has many advantages over using petroleum as a polymer source.
