Plastics and Polymers: A Comprehensive Overview: Introduction to Plastics: Plastics are artificial or synthetic materials that are made up of polymers, which are basically the large molecules composed of repeating structural units called monomers. They are versatile materials usually used in a wide range of applications because of their durability, flexibility, and production at low cost. Types of Plastics: Thermoplastics: These plastics can be melted and reshaped or molded multiple times without undergoesthrough chemical changes. Examples include polyethylene, polypropylene, and polystyrene. Thermosetting Plastics: These plastics harden irreversibly upon heating and cannot be reused or remolded. Examples include epoxy resins and phenolic resins. Biodegradable Plastics: These plastics can be degradable decomposed by microorganisms, reducing environmental impact. Examples include polylactic acid (PLA) and polyhydroxyalkanoates (PHA). Polymerization Process: Polymers are formed by...
