Problems solved by technology

If the chain of the Rf group is short, there is a tendency that the crystallinity of Rf decreases and the oil repellency also decreases, and the treated article is easily contaminated with oil.

Abstract

The invention relates to a fluorine-containing copolymer, which takes: (A) repeating units derived from a fluorine-containing macromonomer of the general formula: CH2=C(-X)-COO-(Y)1-Z-MmMn-H (I) and (B) repeating units derived from poly alkylene glycol (meth) acrylic ester as necessary ingredients, in the formula (I), X is hydrogen atom or methyl, Y is -CH2CH(OH)CH2- or R<1>-NHCO-; l is 0 or 1; Z is -L1-L2-S-(wherein L1 is direct bonding, -O-, -COO- or -NH-, L2 is alkylidene group or aryl, S represents sulphur atom); MmMn is a fluorine-containing oligomer composed by m units derived from fluorine-containing monomers (M) and n units derived from fluorine-non-containing monomers (M). The fluorine-containing copolymer provides durability for maintenance of washing, and has the decontaminant with excellent oil removing property, antifouling property and decontamination property.

Description

technical field The present invention relates to a fluorine-containing copolymer that imparts excellent oil repellency, stain resistance, and stain release properties to fiber products and the like, and is excellent in washing durability. Background technique As an antifouling finishing agent that imparts water and oil repellency to fiber fabrics, etc., and is easy to remove stains attached to fibers by washing, etc., (meth)acrylates (hereinafter also referred to as fluorine-containing compounds) having fluoroalkyl groups are known. ) and a hydrophilic group-containing compound (see JP-A-53-134786, JP-A-59-204980, JP-A-62-7782). However, fiber fabrics and the like treated with these fluorine-containing copolymers cannot be said to necessarily satisfy washing durability, and in addition, there are cases where sufficient and satisfactory detergency cannot be achieved for stubborn stains (such as waste oil such as used engine oil). trend. In order to obtain sufficient deter...
