Abstract: The invention relates to a method of polymerizing at least one fluorinated monomer comprising an ethylene bond, the method comprising putting in contact the at least one fluorinated monomer with a polymerization initiator and a chain transfer agent, the chain transfer agent being a polysulfide compound, preferably a disulfide compound. The invention also relates to a telechelic fluoride-based polymer obtained with said method.

Abstract: The invention relates to a composition of peptides having an aminogram in which: glycine, hydroxyproline and proline are in molar quantities such that the ratio of each quantity to the sum of the molar quantities of the amino acids in the composition is comprised between 20.0% and 24.5%, between 6.0% and 12.0% and between 10.6% and 14.6%, respectively; the peptide composition comprising a quantity of peptides with a molecular weight lower than 1400 Da such that the ratio of said quantity to the quantity of peptides in the composition is less than 40%; the molecular weight and the quantity of peptides in the composition being determined by exclusion chromatography. The invention likewise relates to such a composition to be used as a drug. The invention further relates to such a composition to be used as a food supplement.

Abstract: This invention pertains to the area of orthodontic apparatuses, particularly those that have been precisely adapted to the specific morphology of each patient. The invention proposes a preform dissimilar to a plate; the form of which allows it to expand within a mold that reproduces a patient's morphology; it may be mass produced and easily adapted by the practitioner or prosthesis maker to each patient's morphology as well as orthodontic or dento-facial orthopedic apparatuses obtained from this preform and their manufacture process. Such apparatuses are, for example, Bonnet's N.L.E. (Nighttime Lingual Envelopes—Enveloppe Linguale Nocturne) or any apparatus presenting a general hollow body form, possibly with one or more openings, varying thickness, and which, because of this specific geometry, cannot be produced from a model in the form of a flat plate.
