Problems solved by technology

For the above reasons, there is a problem in (meth)acrylate polymers having a fluoroalkyl group having a side chain whose carbon number is as short as 7 (especially 6 or less) because the crystallinity of the side chain is low. Directly meet the practical performance
In addition, in the water and oil repellent processing, there is the following problem: many additives such as softeners and antistatic agents are used in combination, and the practical performance cannot be satisfied when these agents are used in combination
However, the washing durability has not been sufficiently studied
In addition, Japanese PCT Publication No. 2010-534740 discloses various fluorinated monomers, but there is no particular description or research on the combined use of fluorinated monomers.

After nitrogen substitution in the flask, 61.2 g of vinyl chloride (VCM) was press-filled, 0.4 g of an azo group-containing water-soluble initiator was added, and the reaction was carried out at 60° C. for 20 hours to obtain an aqueous polymer dispersion. The composition of the polymer is substantially identical to that of the feed monomer.

Abstract

The present invention provides a fluoropolymer capable of giving excellent washing durability and water and oil repellency to fibers. The fluoropolymer has a repeating unit derived from a fluorine-containing monomer (a) containing a first fluorine-containing monomer (a1) and a second fluorine-containing monomer (a2), and the first fluorine-containing monomer (a1) is represented by CH2=C(-X1)-C(=O)-Y1-Z1-Rf1, wherein X1 is a halogen atom, Y1 is-O-or-NH-, Z1 is a valence bond or a divalent organic group, Rf1 is a fluoroalkyl group having 1 to 20 carbon atoms, the second fluorine-containing monomer (a2) is represented by CH2=C(-X2)-C(=O)-Y2-Z2-Rf2, in the formula, X2 is a monovalent organic group or a hydrogen atom, Y2 is-O-or-NH-, Z2 is a valence bond or a divalent organic group, and Rf2 isa fluoroalkyl group having 1 to 20 carbon atoms.

Description

technical field [0001] The present invention relates to a surface treatment agent composition such as a fluorine-containing polymer and a water and oil repellent composition containing the same. Specifically, the present invention relates to a method capable of imparting excellent water repellency, oil repellency, and antifouling properties to fiber products (such as blankets), paper, non-woven fabrics, stone materials, electrostatic filters, dust masks, and components of fuel cells. water and oil repellent composition. Background technique [0002] Currently, various fluorine-containing compounds have been proposed. Fluorine-containing compounds have the advantage of being excellent in properties such as heat resistance, oxidation resistance, and weather resistance. Fluorine-containing compounds are used as water and oil repellents and antifouling agents, for example, by taking advantage of their low free energy, that is, the property that they are difficult to adhere. ...
