CA 2562593

A fluorine-containing polymer which comprises (a) a fluorine-containing (meth)acrylate monomer and (b) a nitrogen-containing monomer represented by the general formula (I): [wherein R20 represents a hydrogen atom or a group containing a sulfonic acid group, R21 represents a hydrogen atom or an alkyl group having one to four carbon atoms, and R22 represents a hydrogen atom or a methyl group]; and a treating agent composition comprising said fluorine- containing polymer. The fluorine-containing polymer and the treating agent composition can be used for imparting satisfactory water repellency and oil resistance to a sheet of paper by the use of a reduced amount thereof.

Un polymère contenant du fluor qui comprend (a) un monomère d'acrylate ou de méthacrylate contenant du fluor et (b) un monomère contenant de l'azote représenté par la formule générale : [dans laquelle R?20¿ représente un atome d'hydrogène ou un groupement contenant un groupement d'acide sulfonique, R?21¿ représente un atome d'hydrogène ou un groupement alkyle comportant de un à quatre atomes de carbone et R?22¿ représente un atome d'hydrogène ou un groupement méthyle], et une composition d'agent de traitement comprenant le dit polymère contenant du fluor. Le polymère contenant du fluor et la composition d'agent de traitement peuvent être utilisés pour communiquer à une feuille de papier une excellente résistance au mouillage par l'eau et une excellente résistance à l'huile grâce à l'utilisation d'une quantité réduite de ceux-ci.
