Which of the following is a synthetic polymer?

Which of the following is not natural polymer?

Cellulose rayon

Which one of the following is an example of natural mucoadhesive polymer?

There are many natural polymers that can be used for mucoadhesive buccal film applications, including chitosan and sodium alginate.

Which one of the following is natural polymer?

Natural polmers are found in nature and can also be extracted. These polymers are usually water-based. Silk, wool, DNA and cellulose are all examples of naturally occurring polymers. We mentioned pectin and vulcanized rubber in our section on network polymers.

Which of the following is not a synthetic polymer?


Is Nylon a synthetic polymer?

Nylon is a synthetic plastic material made of high molecular-weight polyamides. It is usually manufactured as a fiber, but it can be used in other cases. Nylons were developed in the 1930s by a research team headed by an American chemist, Wallace H.

Is Dacron a synthetic polymer?

Note : Dacron, also known as Terylene, is a synthetic polymer called Polyester. It is used as a fabric in the textile industry, and in plastic industry as strong thermosetting plastic for making plastic bottles, articles, etc. It is also used as a resin.

Is cellulose a condensation polymer?

Cellulose can be described as a condensation-polymer. It is produced via either a condensation polymerisation process or a series condensation reactions. A condensation reaction is a reaction between two or more monomers and the elimination of small molecules, which in this case is water, but not always.

Which linkage is present in cellulose?

4-glycosidic bonds

What is the difference between cellulose and starch?

Starch can be made from alpha glucose while cellulose is made from beta glucose. Different linkages can lead to different 3-D structures and functions. Starch can be branched or straight and can be used to store energy for plants. It can also form compact structures that can easily be broken down.

How cellulose is formed from glucose?

Cellulose can be synthesized using the enzyme cellulose synase. This membrane protein catalyzes direct polymerization (from UDP-glucose) of glucose into a cellulose product. Many bacteria, Dictyostelium discoideum, as well as higher plants, have genes that can be used to synthesize cellulose.
