When polymers are recycled, the ends of the long chain polymer molecules tend to break off, and this process eventually results in a degradation of physical properties, rendering the cycled polymer unusable. Why the breaking off the end of the polymer molecules is favorable from the stand point of the entropy of the system is needs to be explained. Concept introduction: Entropy is explained as degree of randomness in a system. If there are more number of molecules more will be the entropy. In polymerization , monomers combined to form polymer, thus, molecules are in more ordered form and entropy of system decreases. Opposite to this, if polymers are recycled, due to breaking of long chains of polymer, molecules are no more in ordered form. Hence, entropy increases.

Answer 1

Question

Definition Definition Chemical process in which one or more monomers combine to produce a very large chain-like molecule called a polymer. The functional groups present on the monomers and their steric effects are responsible for polymerization through a sequence of reactions that vary in complexity. There exists a stable covalent chemical bond between monomers that sets apart polymerization from other processes.
