What type of bonds do polymers have?

Polymers are large molecules made up of repeating structural units, typically connected by covalent bonds. These bonds form when atoms share pairs of electrons, allowing for strong connections between the monomers that make up the polymer chain. The strength and stability provided by covalent bonds enable the unique properties of polymers, such as flexibility, durability, and resistance to various environmental factors.

While polymers may exhibit intermolecular forces such as hydrogen bonds or ionic interactions in certain circumstances (particularly in polymer blends or composites), the primary connection between the repeating units in a polymer is through covalent bonds. This is fundamental to their structure and function.
