Answer :
The polymer bond kind in those polymers that cause them to biodegradable: hydrolyzable ester bonds.
Polymers are held together by means of primary bonds (covalent bonds) and secondary bonds (van der Waals and hydrogen bonds). In covalent bonding, there's a sharing of valence electrons (the s and p shells) to complete an octet (a set of 8 electrons) round atoms.
Polymers are large molecules made up of atoms joined collectively by strong covalent bonds. The intermolecular forces among polymer molecules are a whole lot more potent than in small molecules because the molecules are large. Proteins, carbohydrates, nucleic acids, and lipids are the 4 predominant training of biological macromolecules—big molecules vital for life that can be constructed from smaller organic molecules. Macromolecules are made up of unmarried devices referred to as monomers which can be joined by covalent bonds to form large polymers.
