Synthesis and characterization of semifluorinated polymers via group transfer polymerization

Photochemical Stability of Partially Fluorinated Acrylic Protective Coatings. 2. Copolymers of 1H,1H,2H,2H-Perfluorodecyl Methacrylate with Unfluorinated Acrylic Esters

“…All the copolymers present good solubility in common organic solvents, allowing their potential use in the formulation of coatings. Some of the above polymers have already demonstrated their good protective action when applied on stone, particularly in terms of water repellency and film-forming properties. − These earlier studies also showed that fluorinated units having appropriate fluorine amount and distribution should be combined with polar co-units in order to give a good anchorage onto the working surface and allowing, in addition, a modulation of the glass transition temperature, T g , and of other material properties …”

The synthesis and enhancement of the surface properties of polyfluorene-based photoelectric materials by introducing fluoromonomers

“…a poor solubility in THF and a presumably rather collapsed coil structure. 45,46 Therefore, the experimental molecular weights determined by GPC should only be regarded qualitatively. Therefore, the GPC measurements and the 1 H NMR method were used to confirm the molecular weights (M n ) of PF-OH, PF-Br and the PF-b-PHFBMA diblock copolymers, 47,48 and the corresponding results are listed in Table 1.…”

Fluorine‐Containing Block Copolymers: Synthesis and Application as a Template for Nanocellular and Porous Structures Using Supercritical Carbon Dioxide

“…Group-transfer polymerization (GTP) is also effective to produce AB diblock copolymers of MMA with alkyl methacrylate bearing either a perfluorobutylethyl or perfluorohexylethyl group (Krupers and M€ oller, 1997a;Krupers and M€ oller, 1997b). Unfortunately, a monomer with a long perfluorooctylethyl group is difficult to polymerize due to a solubility problem, even in sequential polymerization using a second monomer.…”
