Polymers are made up of units
WebPolymers: Polymers are large molecules made up of repeating units called monomers. Examples of polymers include plastics, rubber, and DNA. Polymers can be classified based on their structure, such as linear, branched, or cross- linked. WebOct 29, 2024 · It is also the simplest polymer, consisting of random-length (but generally very long) chains made up of two-carbon units. Figure 12.2.4. 1: Polymers. Ethylene is shown as a monomer. A long chain containing multiple repeating ethylene is known as polyethylene which is a polymer.
