Cross-link
Cross-link
Cross-link (pronounced: /ˈkrɔːs lɪŋk/) is a bond that links one polymer chain to another. They can be covalent bonds or ionic bonds.
Etymology
The term "cross-link" was coined in the early 20th century as chemists began to understand the structure of polymers and the nature of their connections. The term is derived from the English words "cross," meaning to intersect or join, and "link," meaning a connecting element or factor.
Definition
In polymer chemistry, a cross-link is a bond that connects one polymer chain to another. These links can take the form of covalent bonds or ionic bonds. Cross-links are critical in both the creation and function of many polymers, as they provide the structure and strength necessary for the polymer to perform its intended function.
