Question

3.- Explain the variables in the Carothers equation, and its physical meaning. How can this equation be used to control a step polymerization and its molecular weight?

4.- Explain why an acid catalyzed polyesterification proceeds at a faster rate than a non-catalyzed polyesterification. Use: a) mechanism of the reaction from a synthetic perspective, and b) Carothers equation to start your discussion, followed by any other equation that explains it from a kinetic standpoint.

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.
