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... WebPolymers are held together by primary bonds (covalent bonds) and secondary bonds (van der Waals and hydrogen bonds). In covalent bonding there is a sharing of valence electrons (the s and p shells) to complete an octet (a group of eight electrons) around atoms. The most notable exception to this octet is hydrogen, needing only two electrons.
