Ques 6. The backbones of common synthetic polymers are made of carbon-carbon bonds, whereas heterochain polymers have other elements (e.g. Synthetic condensation polymers. Unlike natural fibres, synthetic fibres are more durable, elastic, strong, soft, cheap, and do not wrinkle easily. The most common examples of the natural polymers are DNA, cellulose, silk, wool, and proteins, on the other hand, the most common examples of synthetic polymers are polyethylene, polyester, nylon, Teflon and epoxy. Polyamides and polyesters are two groups of synthetic fibres with high strength, not easily stretched and used as textile. Monomers have the ability to react with another molecule from the same type or another type in the suitable condition to form the polymer chain. Natural Polymers vs. Synthetic polymers are commonly known as plastics. . Synthetic rubbers (Buna-5), synthetic fibres (nylon 6, 6), and plastics are all examples of synthetic polymers (polythene).

Other common examples are protein (found in humans and animals alike), Cellulose and starch (found in plants), or Rubber (which we harvest from a host plant). Synthetic polymers can either be organic or inorganic polymers. Based on their structure, the polymers can be classified into three types such as linear polymers, branched-chain polymers, and network, or cross linked polymers. A polymer is made up of smaller repeating units known as monomers. Elastomers regain their original shape after being distorted in a physical process. These macromolecules are present in virtually everything that surrounds us. The word polymer comes from two Greek words: poly, meaning many, and meros, meaning parts or units. Plastics, which are manufactured polymers, are frequently referred to as polymers. What are biodegradable polymers give an example of such a polymer and mention its uses?

Polymers can be created using the process of polymerization. Thus, they are used to produce caps, raincoats, sportswear and ropes. This was due to the need to replace Asian silk and hemp in parachutes during World War II. In addition to being durable, synthetic materials offer consumer-friendly features, such as stretchable, waterproof . Synthetic polymers . Synthetic polymers may be grouped into two categories. Synthetic polymers are polymers made by man through chemical reactions in industry from polymerisation of monomers. Semi-synthetic polymers are those that are derived from nature itself but are made to undergo chemical processes to enhance their quality. Polyethylene is utilised in bottles, electrical insulation, toys, etc Synthetic polymers are chemicals made by rearranging the structure of existing molecules, especially large molecules containing carbon. The term "Polymer" has its origin in the Greek word "polus meros" which means many (polus) parts (meros). See answer (1) Best Answer. Polysaccharides, such as cellulose and starch are some examples of natural polymers. Synthetic polymers are those that are created especially. Properties of a Polymer The properties of a polymer are affected by the structure, type of monomer units from which polymers are formed, and other factors.
