condensation polymerization

[‚kän·dən′sā·shən pə‚lim·ə·rə′zā·shən]
(organic chemistry)
The stepwise reaction between functional groups of reactants in which a high-molecular-weight polymer is formed only after a large number of steps, for example, the reaction of dicarboxylic acids with diamines to form a polyamide.

First, the copolymer can be synthesized using mild conditions via cationic polymerization instead of high temperature melt condensation polymerization. (17,18) Secondly, the potential for gelation during resin manufacture that exists for alkyd synthesis is eliminated using the cationic addition polymerization previously developed.
The condensation polymerization may be exemplified by the following process:
In this work, poly[(2-hydroxyethyl methacrylate)-graft-poly(lactic acid)-phosphazene] and poly[bis(2-hydroxyethyl-methacrylate)-phosphazene] were synthesized by condensation polymerization reactions.
A novel slow-release nitrogen fertilizer poly(carbonyl urea)oligomer (PCUO) was prepared by the condensation polymerization of urea and dipropyl carbonate (DPrC) at normal pressure, in which anhydrous potassium carbonate was as a catalyst.
One of the established facts was the equal reactivity hypothesis for modeling of irreversible condensation polymerization in batch reactors, whose consequences were verified by definitive experiments.
Like the TPUs many structural and compositional variations are possible due to the richness of the condensation polymerization chemistry involved.
