WebApr 2, 2014 · Cross-link is a bond which links one polymer chain to other. It can be ionic or covalent. Cross linking changes a liquid polymer into ‘solid’ or ‘gel’ by restricting the ability of movement. When polymer chains are … WebJun 5, 2024 · The cross-linking process is a physical or chemical linkage between two polymer chains (Fig. 1 ). It could be physical reaction through van der Waals forces, H-bond, or dipole-dipole interactions, leading to the formation of thermoplastic polymers.
Cross-linking Definition & Meaning - Merriam-Webster
In chemistry and biology a cross-link is a bond or a short sequence of bonds that links one polymer chain to another. These links may take the form of covalent bonds or ionic bonds and the polymers can be either synthetic polymers or natural polymers (such as proteins).
