Of all the four types of bonds, Van der Waals is the weakest. For this reason, polymers are very elastic (e.g., a rubber band), can be easily melted, and have low strength.
WebIn 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).. In polymer chemistry "cross-linking" usually refers to the use of cross-links to …
WebProperties of Polymers. Polymers are large molecules built up of repeating units called monomers. Addition polymers are formed from monomers with a C=C double bond.
