Title (EN) FLUOROCHEMICAL COMPOSITION COMPRISING A POLYURETHANE HAVING A FLUOROCHEMICAL OLIGOMER AND A HYDROPHILIC SEGMENT TO IMPART STAIN RELEASE PROPERTIES TO A SUBSTRATE
(FR) COMPOSITION FLUOREE RENFERMANT UN POLYURETHANNE QUI POSSEDE UN OLIGOMERE FLUORE ET UN SEGMENT HYDROPHILE POUR CONFERER DES PROPRIETES FACILITANT LE LAVAGE A UN SUBSTRAT
Abstract:
(EN) The present invention provides a method for preparing a fluorochemical composition comprising polyurethane by reacting: (A) fluorochemical oligomer of formula (I): MfmMn-Q1-T1 wherein: MfmMn represents flurochemical oligomer comprising m units derived from fluorinated monomer and n units derived from fluorine-free monomer and wherein the fluorinated monomers and fluorine-free monomers may be the same or different; m represents a value of 2 to 40; n represents a value of 0 to 20; T1 is -OH or -NH2; Q1 and T1 together represent an organic residue obtained by removing a hydrogen atom from a chain transfer agent that is functionalized with T1; and (B) difunctional compound capable of reacting with an isocyanate and comprising a poly(oxyalkylene) group having 18 to 280 oxyalkylene moieties with (C) diisocyanate or triisocyanate. Substrates treated with the fluorochemical composition prepared according to the method described above, have good stain release properties in particular for oily stains and water based stains such as wine, tea and coffee.
(FR) La présente invention concerne un procédé permettant de préparer une composition fluorée renfermant un polyuréthanne, par la mise en réaction de: (A) un oligomère fluoré représenté par la formule (I): MfmMn-Q1-T1, dans laquelle MfmMn représente un oligomère fluoré doté de m unités obtenues à partir d'un monomère fluoré, et de n unités obtenues à partir d'un monomère exempt de fluor, les monomères fluorés et les monomères exempts de fluor pouvant être les mêmes ou différents; m représente une valeur comprise entre 2 et 40; n représente une valeur comprise entre 0 et 20; T1 est -OH ou -NH2; Q1 et T1 représentent ensemble un résidu organique obtenu par élimination d'un atome d'hydrogène d'un agent de transfert de chaîne qui est fonctionnalisé avec T1; et (B) un composé difonctionnel capable de réagir avec un isocyanate, et comportant un groupe poly(oxyalkylène) possédant de 18 à 280 fractions oxyalkylène; avec (C) un diisocyanate ou un triisocyanate. Des substrats traités avec la composition fluorée, préparée selon le procédé décrit, présentent de bonnes propriétés facilitant le lavage, en particulier à l'égard de taches de graisse et de taches à base d'eau telles que des taches de vin, de thé et de café.
