FAQs on Polymers

How polymer is made?

Polymers are large molecules made up of smaller linked molecules called monomers. If you have ever eaten or worn plastic, aspirin or a pair of fibres from a pair of nylon stockings, you have used a polymer.

How polymers are classified?

Polymers are classified into two broad categories, natural polymers and synthetic polymers.

How polymers are formed?

A polymer is a large molecule made up of smaller, joined-together molecules called monomers. … Monomers join together to make polymer chains by forming covalent bonds—that is, by sharing electrons. Other bonds then hold the groups of chains together to form a polymer material.

How polymer clay is made?

Polymer clay is created by combining PVC that contains oils with a plasticizer to give it something of an oily texture. The ingredients are mixed at high temperatures, formed into pellets of soft brown material, and then cooled.

How polymers are classified on the basis of their structure?

Polymers can be classified into three main types based on structure. These are linear polymers, branched chain polymers and cross- linking polymers.

How polymers affect the environment?

Every year, the world produces millions of tons of plastic. The majority of it gets thrown away as non-biodegradable waste because of its non-biodegradable nature. As a result, the used polymeric products like plastic bags and bottles cannot be dumped in sanitary landfills. These synthetic waste items are then combust in the incinerators which results in release of harmful gases and cause air pollution.
