Mn2(CO)10‐Visible Light Photomediated, Controlled Radical Polymerization of Main Chain Fluorinated Monomers and Synthesis of Block Copolymers Thereof
Open accessAbstract
This chapter demonstrates that metal-catalyzed initiation of the polymerization of main chain fluorinated gaseous monomers such as vinylidene fluoride (VDF), can easily be accomplished at 0–100°C, including at rt upto 40°C, directly from a wide variety of alkyl, semifluorinated and perfluoroalkyl halides (Cl, Br, I), using a visible light, Mn2(CO)10 photomediated protocol, carried out in low pressure glass tubes, and which is especially successful in dimethyl carbonate. Fluoropolymers constitute a fundamental class of specialty materials endowed with wide morphological versatility, high thermal, chemical, aging, and weather resistance, as well as low surface energy, dielectric constant, flammability, refractive index, and moisture absorption. Typical VDF laboratory polymerizations are carried out in acetonitrile (ACN) that is a nonsolvent and a weak chain transfer agent (CTA).

One criterion used by 3M Company to screen and select its replacement to PFOA in fluoropolymer production (ADONA) was that the alternative fulfills all requirements for the polymerization process with minor process adjustments.
“one of the criteria used by 3M Company to screen and select its replacement to PFOA in the production process of fluoropolymers (i.e., ADONA)6 was that the alternative”

The Introduction (§2.1) and Solvent Effect (§2.3.2) discuss fluoropolymerization methods and solvent selection, but do not address 3M’s selection of ADONA. Searches for ADONA, PFOA, 3M, and minor process adjustments found no passage supporting the stated criterion. Page numbers were not available in our copy. (LLM, conf=0.74)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
