WebThe disassembly of polymers is important because breaking the chemical bonds releases this energy into the system. Polymers may also serve a structural function in biological or synthetic systems (e.g., cellulose in plants, nylon in fabric). In general, the function of a polymer depends on the chemical composition of its monomers. WebPolymers are formed by two main ways called addition and condensation polymerization. In addition, polymerization, an initiator (or catalyst) reacts with a starting monomer. The …
