Classification of polymers flowchart
What are the classification of polymers?
Classification of Polymers based on the Source of Availability. There are three types of classification under this category, namely, Natural, Synthetic, and Semi-synthetic Polymers.
What are the 4 classes of polymers?
There are four basic kinds of biological macromolecules: carbohydrates, lipids, proteins, and nucleic acids. These polymers are composed of different monomers and serve different functions.
What are the 3 classifications 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. Thermoplastic polymers can be either amorphous or crystalline.
How polymers are classified give examples?
On the basis of source polymers are classified as: Natural polymers (Example: Starch, Cellulose, Portions, etc.) Synthetic polymers (Example: PVC, -Nylon Teflon, etc.) Semi-synthetic polymers (Example.
What is polymer and its types?
Difference Between Thermosetting and Thermoplastic Polymers
| Thermoplastics Polymer | Thermosetting Polymer |
|---|---|
| Formed by Addition Polymerisation | Formed by Condensation Polymerisation |
| Have a Bifunctional monomer | Have a Trifunctional, Polyfunctional monomer |
| Long-chain, linear polymers | Three-dimensional network |

What are 3 properties of polymers?
Some of the useful properties of various en- gineering 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.
What is a polymer class 8?
A synthetic fibre is also a chain of small units joined together. Each small unit is actually a chemical substance. Many such small units combine to form a large single unit called a polymer.
How many polymers are there?
There are two types of polymers: synthetic and natural.
What are the two categories of polymers?
Polymers fall into two categories: thermosetting plastic or thermoset. thermoforming plastic or thermoplastic.
What are natural polymers How are they classified?
Natural polymers, also called biopolymers, are naturally occurring materials, formed during the life cycles of green plants, animals, bacteria, and fungi. They are classified mainly into three groups: polysaccharides, polypeptides, and polynucleotides [26–28].
What are 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.
What is polymer structure?
A polymer is composed of many simple molecules that are repeating structural units called monomers. A single polymer molecule may consist of hundreds to a million monomers and may have a linear, branched, or network structure.
What are the uses of polymers?
Product made from polymers are all around us: clothing made from synthetic fibers, polyethylene cups, fiberglass, nylon bearings, plastic bags, polymer-based paints, epoxy glue, polyurethane foam cushion, silicone heart valves, and Teflon-coated cookware. The list is almost endless.
What is the origin of polymers?
Most polymers are obtained from crude oil often found deep within the Earth’s crust . It is accessed by drilling, which can be a costly and messy process. Some polymers can be derived from natural sources, such as plants.
What are polymers explain?
A polymer is any of a class of natural or synthetic substances composed of very large molecules, called macromolecules, which are multiples of simpler chemical units called monomers. Polymers make up many of the materials in living organisms and are the basis of many minerals and man-made materials.
