Telomerization (polymerization)

Fluorotelomer alcohol ( 8: 2 FTOH )

The telomerization or telomerization is a chemical reaction that a special form of polymerization represents.

A molecule A – B reacts with n molecules of the monomer M to form telomeres according to the following equation:

${\displaystyle \mathrm {{\text{A--B}}+n\cdot M\rightarrow {\text{A--M}}_{n}{\text{--B}}} }$

Fluorotelomerization

In the manufacturing process of perfluorinated surfactants such as fluorotelomer alcohols , fluorotelomerization, one process step consists of telomerization. In addition to electrochemical fluorination , it represents the second process for the production of perfluorinated surfactants. Here, n molecules of tetrafluoroethylene are reacted with pentafluoroethyl iodide :

${\displaystyle \mathrm {F(CF_{2}CF_{2})I+n\cdot CF_{2}{\text{=}}CF_{2}\rightarrow F(CF_{2}CF_{2})_{n+1}I} }$
