Answer it fast . It is related to the thermoplastic and thermosetting plastic
Answers
Answer:
These types of arrangements can be seen in thermoplastics (first) and in thermosetting plastics (second).
Explanation:
Thermoplastics are polymers that are usually formed by addition polymerization and have linear molecular chains. These types of plastics can be easily bent and molded into different shapes. They can be softened multiple times by heating. This is used in making containers like bottles of shampoo, Drinking water, food, etc., and in CDs, DVDs. Also used in automobile parts. Polymers like Polyethylene, polystyrene, PVC are some of the thermoplastics.
Thermosetting Plastics are usually formed by condensation polymerization and have cross-linked molecular chains. They cannot bend, soften, and be molded into another shape by heating. Such plastics are strong and harder. These are used in making electrical components, construction equipment panels, circuit breakers, etc. Bakelite, Duroplast, vulcanized rubber are some of the thermosetting plastics.
