Question

Polyblend, a fine powder of recycled modified plastic, has proved to be a great material for
A. Making plastic sacks
B. Use as a fertilizer
C. Construction of roads
D. Making tubes are pipes

Answer 1

Hint: Plastics are modified or recycled for many applications. Polythene polyester polymer called as Polyblend is obtained from recycled modified plastic and it has the property of crash and shrink resistant layers. We can use it for construction purposes also.

Complete step by step answer: When the two polymers blend together to create a new material with different physical properties this polymer mixture is called a polymer blend as polymerization is the first technique used for the modifications in polymers.
Thomas Hancock got a mixture of natural rubber with gutta-percha. This process leads to the production of new polymer classes called polymer blends. Three types of blends are found that are immiscible, compatible, and miscible polymer blends. Polyblend is the fine powder of recycled modified plastic that is developed by a Bangalore based company. Mixing of this polymer is done to use it for many purposes. When it is mixed with bitumen it can be used to lay roads.
 As we know that accumulation of plastic waste is a very serious problem so the plastic sack manufacturers in Bangalore find an ideal solution for this problem. They form a mixture of Polyblend and bitumen and use it to lay or construct roads, they have found that this Polyblend and bitumen shows water repellant properties and helped to increase the life time of the road three times.
From the above information we have found that Polyblend mix with bitumen is used to construct roads.
So the correct answer is option C.

Note: Polyblends have various applications in science, textiles, material science and environment. Nowadays plastic recycling is an important task. Plastic increases the melting point of bitumen so that melting point of polymer can be prevented in hot and humid climates as in India. It is also good, as rainwater will not seep through it because it is a plastic polymer.
