Which is an example of a polymer 1 point?
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 polymers 12?
A polymer is a large molecule of high molecular mass formed by the repetitive bonding of many small molecules called monomers. The process by which the monomers are transformed into polymers is called polymerisation. As polymers are single big size molecules, they are also called macromolecules. 2.
What are artificial polymers?
Synthetic polymers are human-made polymers, often derived from petroleum oil. From the utility point of view they can be classified into three main categories: thermoplastics, elastomers and synthetic fibers. A wide variety of synthetic polymers are available with variations in main chain as well as side chains.
What is cellulose polymer?
Cellulose is a linear polymer glucan and is composed of glucose units (> 10 000), which are linked by β-(1–4)-glycosidic bonds. The regular arrangement of the hydroxyl groups along the cellulose chain leads to the formation of H-bridges and therefore to a fibrillar structure with crystalline properties.
What are the two main types of polymers?
Polymers are of two types: naturally occurring and synthetic or man made.
What is the main properties of polymers?
Some of the useful properties of various engineering polymers are high strength or modulus to weight ratios (light weight but comparatively stiff and strong), toughness, resilience, resistance to corrosion, lack of conductivity (heat and electrical), color, transparency, processing, and low cost.
Which polymers contain nitrogen?
Nylon is a polymer which contains nitrogen.
What is a polymer give two examples?
Polymers may be divided into two categories. Natural polymers (also called biopolymers) include silk, rubber, cellulose, wool, amber, keratin, collagen, starch, DNA, and shellac. Examples of synthetic polymers include PVC (polyvinyl chloride), polystyrene, synthetic rubber, silicone, polyethylene, neoprene, and nylon.
