Polymers types of bonds
WebThere are numerous types of bonds in polymer engineering, however, they can largely be broken up into primary and secondary bonds. Primary polymer bonds cons... WebThis reference indicates that primary bonds in a polymer are the intramolecular bonds (the covalent bonds) that hold the polymer together. Cross-linking different chains of polymer together does occur through a covalent bond, such as a disulfide bond. The secondary bonds that help to give the polymer its physical properties are intermolecular forces, such …
