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. WebIn polymers, the intermolecular forces binding polymer molecules together are classified as weak, meaning that these forces arise from bonds that are typically less than 5 kilocalories per mole.
