Explanation
Polymers consist of long chains of monomers linked by covalent bonds. Plastics, rubber, and synthetic fibers are polymers. Natural polymers include proteins, cellulose, and DNA. Polymers have many industrial applications due to their properties. Polymer properties depend on monomer type, chain length, and cross-linking. Thermoplastics can be melted and reshaped while thermosets cannot.
Example
Polyethylene is a polymer of ethylene monomers used in plastic bags and containers.
