Although the words ‘polymer’ and ‘plastic’ are often used interchangeably, plastics are actually just one kind of polymer. They’re polymers that have plasticity. In other words, they can be moulded—using heat, for example. Nitrogen data of plastics additives. Table 4. Nitrogen data of polymers (pellets). Table 5.
Polyvinyl chloride (PVC) has chlorine attached to the all-carbon backbone. Teflon has fluorine attached to the all-carbon backbone. You guessed it – if there is another conjoined monomer (not a mechanical blend), you got a CO polymer. Examples: “ethylene vinyl acetate” or EVA for short – vinyl acetate monomer married to ethylene monomer, “styrene butadiene styrene” or SBS – styrene and butadiene building blocks, A very cool copolyester is Eastman’s Tritan. Metallized plastics are used to replace metal objects by plastics for example to reduce the weight of a product of both the conductive metal and the insulating plastic form a functional unit as in the case of a printed circuit board or film. Since metals generally bond poorly to polymers, the plastic surface has to be treated. 1 Source: Plastics Europe, Association of Plastics Manufacturers, World Thermoplastics Demand by Types 2015.

We'll focus the rest of this tutorial on synthetic polymers. The common name to synthetically made polymers is plastics which are used very frequently in our day-to-day lives. –> Plasticizers: base polymers are often rigid and do not have the necessary flexibility and rheology, or flow, properties that are needed for plastics processing. Plasticizers are added to improve rheology as well as elasticity.

What is a polymer give few examples of polymers that you encounter in everyday life? Examples of synthetic polymers include nylon, polyethylene, polyester, Teflon, and epoxy.
Table 4. Nitrogen data of polymers (pellets). Table 5. Nitrogen data of polycarbonate polymers (pellets). Table 4 shows the nitrogen data of polymers in pellets. The system was calibrated with 10–12 mg atropine standard using K factor as calibration method. Samples 1 and 2 were weighed at 200–250 mg.

Examples of polymers Polymers may have the qualities of liquids or solids. Silly Putty is a great example of a polymer with both: when pulled slowly, it is fluid, but if yanked apart it snaps and breaks like a solid. Polyethylene, polypropylene, polybutylene, polystyrene and polymethylpentene are examples of these.
