Polymers are large molecules made up of repeating smaller units called monomers. These monomers are chemically bonded to form long chains or networks.
Types:
Natural PolymersFound in nature. Examples:
Proteins (e.g., in skin and muscles)
Carbohydrates (e.g., starch, cellulose)
DNA (carries genetic information)
Synthetic PolymersMan-made for various applications. Examples:
Plastic (e.g., polyethylene, PVC)
Rubber
Nylon and Teflon
Linear Polymers: Long, straight chains (e.g., PVC).
Branched Polymers: Chains with side branches (e.g., low-density polyethylene).
Cross-linked Polymers: Chains linked by bonds at various points (e.g., Bakelite).
Properties:
Flexible or Rigid depending on structure.
Resistant to chemicals.
Used in packaging, textiles, electronics, and more.
