nCa-AI Collaborative Report 1. What Are Polymers in General? Polymers are macromolecules formed by repeating monomer units linked via covalent bonds. They include natural polymers (e.g., cellulose, proteins) and synthetic ones (e.g., polyethylene, nylon), distinguished by high molecular weight, which confers properties like flexibility, strength, and durability. Synthetic polymers, often derived from petrochemicals, dominate modern […]
