a chain reaction involving unsaturated compounds (monomers) and a substance that acts to propagate the reaction chain. Telomerization produces a mixture of chemical species (telomers) having different molecular weights. The molecules of the products are constructed of monomeric units M, and the products’ end groups are fragments A and B from the propagating substance. Telomerization is described by the general equation:

This type of reaction is a special case of polymerization.

Of the monomers used in telomerization, the most thoroughly investigated are ethylene, α-olefins, vinyl chloride, vinyl acetate, perfluoroethylene, allyl and acrylic compounds, dienes, and diene derivatives. Among the compounds that act as propagating substances are CC14, CHC13, and RCBr2COOCH3. Telomerization is initiated by peroxides, azo compounds, transition-metal compounds, strong mineral and aprotic acids, and alkali metals.

Telomerization underlies processes for synthesizing large-ring lactones (perfumes), ω-amino acids, and higher carboxylic acids.

Consequently, the current production of fluorinated polymers and surfactant is mostly based on telomerization processes (Lehmler 2005).
In the telomerization processes, fluorotelomer iodides are oxidized to produce FTOHs.
There are two main manufacturing methods leading to PFOS and PFOA: electrochemical fluorination (ECF) and telomerization. The 3M Company manufactured the bulk of PFOS (and higher-molecular-weight precursor materials), PFHxS, and PFOA by ECF until 2001, at which time they voluntarily phased out these chemistries.
Therefore, these observations suggest that a significant proportion of PFOA in these house dust samples came from a manufacturing source that used telomerization instead of ECF.
Industrial production of the salts of perfluorooctanoic acid occur through electrochemical fluorination and telomerization. Perfluorooctanoate [PFOA; [CF.sub.3]([CF.sub.2]).sub.6][COO.suP.-]], the dissociated carboxylate anion, has been measured in humans worldwide but generally at lower nanogram per milliliter concentrations than PFOS (Houde et al.
