Types of Polymers on the basis of Method of Preparation

Question

1.- How does the molecular weight change vs % conversion in a step polymerization? Explain this behavior and why does it occur?

2.- Name at least 3 requirements for obtaining a high molecular weight polymer by step polymerization.

3.- How can you minimize cyclization reactions in a step polymerization? Explain with equations and narrative Why do you want to minimize cyclization? Is it possible to eliminate cyclic products completely?

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.
