Polymers have been around us in the natural world since the very beginning (e.g., cellulose, starch, and natural rubber). Man-made polymeric materials have been studied since the middle of the nineteenth century. Today, the polymer industry has rapidly developed and is larger than the copper, steel, aluminum and some other industries combined.4

How are polymers obtained?

Polymers are obtained through chemical reaction of monomers. 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. This process in nature has resulted to the formation of natural polymers, while the synthetic polymers are man-made.

What are monomers in condensation?

These polymers are formed by the combination of monomers, with the elimination of small molecules like water, alcohol etc. The monomers in these types of condensation reactions are bi-functional or tri-functional in nature. A common example is the polymerization of Hexamethylenediamine and adipic acid. to give Nylon – 66, where molecules of water are eliminated in the process.

What type of polymer is brittle?

In this type of polymers, monomers are linked together to form a three-dimensional network. The monomers contain strong covalent bonds as they are composed of bi-functional and tri-functional in nature. These polymers are brittle and hard. Ex:- Bakelite (used in electrical insulators), Melamine etc.

How are polymers formed?

The polymer is formed by polymerization of monomers with double or triple bonds (unsaturated compounds). Note, in this process, there is no elimination of small molecules like water or alcohol etc (no by-product of the process). Addition polymers always have their empirical formulas same as their monomers.

What is the process of reacting monomer molecules together in a chemical reaction?

Polymerization is the process by which monomer molecules are reacted together in a chemical reaction to form a polymer chain (or three-dimensional networks). Based on the type of polymerization , polymers can be classified as:

What are polymers used for?

These polymers have high melting points and are of higher density. A common example of this is PVC (Poly-vinyl chloride). This polymer is largely used for making electric cables and pipes.

How does stress affect rubber bands?

The polymer chains are held by the weakest intermolecular forces, hence allowing the polymer to be stretched. But as you notice removing that stress also results in the rubber band taking up its original form. This happens as we introduce crosslinks between the polymer chains which help it in retracting to its original position, and taking its original form. Our car tyres are made of Vulcanized rubber. This is when we introduce sulphur to cross bond the polymer chains.

What is the structure of polymers?

As the title describes, the structure of these polymers is like branches originating at random points from a single linear chain. Monomers join together to form a long straight chain with some branched chains of different lengths. As a result of these branches, the polymers are not closely packed together. They are of low density having low melting points. Low-density polyethene (LDPE) used in plastic bags and general purpose containers is a common example

What will happen if recycling technology improves?

As recycling technology improves and, hopefully, more attention is called to the importance of recycling, we will see additional methods of reusing plastics and other materials.

How many types of plastic are there?

Plastics are generally sorted by and recycled by type. There are seven types of plastic labeled for recycling purposes. The recycling code is normally on the bottom or side of a container, and is a number within a triangular set of three arrows. Separating and recycling plastics in this way produces a more consistent and higher-quality product.

Why is recycling so tedious?

The problem is that recycling is a tedious process. Mostly, that's because the plastic needs to be separated by type. The problem you'll attempt to solve is whether you can differentiate between various types of plastic, based on their physical and chemical properties.

What is HDPE used for?

This type of plastic is used to make about 60 percent of all plastic bottles, such as those containing milk, detergents, shampoo, bottled water, juices, and antifreeze. It 's also used for plastic grocery bags and freezer bags.

A plastic is a type of polymer. A polymer is a chemical compound that is made up of repeating units of molecules called monomers.

What is PET made of?

Polyethylene terephthalate ( PET ). Nearly a quarter of all plastic bottles-including carbonate beverage bottles-are made from this type of plastic. So are meat wrappers, filling for pillows, and cosmetic wrappings.

How many pieces of plastic do you need for a permanent marker?

To prepare for your experiment, you'll need to cut five samples from each of the plastic containers you've gathered. You need to have five small pieces of type 1 plastic, five of type 2, and so on, through type 6.
