This is further divided into:
Polymers have different applications based on their mechanical properties such as elasticity, tensile strength, etc.
Addition and condensation polymers are also referred to as chain growth polymers.
Polymers that are naturally obtained or extracted from nature (living organisms) are referred to as natural polymers. They are present abundantly in plants, animals and human beings. Natural polymers include proteins, DNA, RNA, starch, glycogen, etc. When having takeaway food, the food is made up of several natural polymers, it can be proteins carbohydrates, etc. The packaging of the food that was delivered such as the packet, plastic containers, one-time use cutlery is also made up of several different polymers.
A variety of monomers react to undergo polymerization to form polymers known as copolymers.
A large number of polymers due to their strong links are very hard to break and therefore be degraded. This causes them to accumulate in the surrounding environment and become toxic and cause an imbalance in nature. To avoid such situations recently new varieties of artificial polymers are being manufactured which can easily be degraded and hence are as much toxic.
