What are Polymers?
Polymers are macromolecules consisting of repeating units linked together by covalent bonds. They can be classified based on their structure, properties, and sources.
Types of Polymers:
- 🔹 Natural Polymers – Found in nature (e.g., proteins, cellulose, rubber).
- 🔹 Synthetic Polymers – Man-made polymers like polyethylene, polystyrene, and nylon.
- 🔹 Thermoplastics – Can be melted and reshaped multiple times.
- 🔹 Thermosetting Polymers – Hard and rigid materials that cannot be remelted.
- 🔹 Biodegradable Polymers – Environmentally friendly alternatives used in medical and packaging industries.
Polymers are an essential part of modern materials science, contributing to innovation in medicine, engineering, and sustainability.
