What is the kinetics of condensation polymerization?
Condensation polymerization proceeds by the reaction of two functional groups, usually with the formation of a volatile by-product. This by-product must be removed in order to drive the polymerization reaction toward comple- tion, with the formation of polymers having high molecu- lar weights.What is condensation polymerization PDF?
Condensation polymerisation is therefore a reaction in which many monomers join together to form a polymer, with the elimination of a smaller molecule such as water each time a monomer joins the chain. Polyesters.What is the mechanism and kinetics of step-growth polymerization?
The kinetics and rates of step-growth polymerization can be described using a polyesterification mechanism. The simple esterification is an acid-catalyzed process in which protonation of the acid is followed by interaction with the alcohol to produce an ester and water.- course of polymerization and the propagation rate (Rp) is expressed by the equation; Rp = kp [P*] [M] (M: the monomer).
