kondensaatiopolyeomeroinnissa

Kondensaatiopolymeerization is a chemical process where monomers react to form a polymer, releasing a small molecule as a byproduct. This small molecule is often water, but can also be methanol, hydrogen chloride, or other substances. The reaction involves the functional groups of the monomers combining, typically with the elimination of the small molecule. This process differs from addition polymerization, where monomers simply add to one another without the loss of any atoms.

Common examples of polymers formed through condensation polymerization include polyesters, polyamides, and polycarbonates. Polyesters are formed from the reaction of diols and dicarboxylic acids, releasing water. Polyamides, such as nylon, are formed from the reaction of diamines and dicarboxylic acids, also releasing water. Polycarbonates are created from the reaction of bisphenols and phosgene or diphenyl carbonate, with the byproduct being phenol or HCl. The rate of condensation polymerization can be influenced by factors such as temperature, catalyst presence, and reactant concentrations. The molecular weight of the resulting polymer can be controlled by the stoichiometry of the reacting monomers and the extent of the reaction.
