Embodiment

[0088] Hereinafter, the present invention will be described in detail with reference to examples.

[0089] The following examples are used to illustrate the present invention, but not to limit the present invention. Unless otherwise stated, parts and percentages (%) hereinafter are parts by weight and percentages by weight (% by weight).

[0090] The test method used is as follows.

[0091] oil resistance

[0092] Oil resistance is determined according to the extension method of TAPPI UM-557. Put a drop of the test oil shown in Table 1 on the paper, and observe the state of oil penetration after 15 seconds. The oil resistance was taken as the highest point of the oil resistance provided by the test oil which showed no penetration.

Synthetic example 1

[0100] Put 22.6 parts of AK-225, 22.6 parts of DMF, 2.79 parts of AMPS and 8.4 parts of fluorine-containing acrylate (V) represented by the following formula into a volume of 100 parts (1L) and equipped with stirring device, thermometer, reflux cooling In the reactor of the device, dropping funnel, nitrogen flow inlet and heating device.

[0101]

[0102] The mixture was exposed to a nitrogen stream for 30 minutes, and after the temperature was raised to 60° C., 0.16 parts of tert-butyl peroxytrimethyl acetate 70% solution was added and reacted for 6 hours. The consumption rate of the fluorine-containing acrylate (V) was determined to be 100% by gas chromatography.

[0103] Then, the reaction mixture was cooled to room temperature. Thus, 56 parts of a transparent solution (S1) having a solid content concentration of 19.8% was obtained.

Synthetic example 2

[0105]The same operation as in Synthesis Example 1 was repeated except that 8.4 parts of fluorine-containing acrylate (V) in Synthesis Example 1 was replaced with 8.4 parts of Fluorine-containing Acrylate (VI) of the following formula. The consumption rate of the fluorine-containing acrylate (VI) was determined to be 100% by gas chromatography. Thus, 56 parts of a transparent amber solution (S2) having a solid content concentration of 20.0% was obtained.

Abstract

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 R<20> represents a hydrogen atom or a group containing a sulfonic acid group, R<21> represents a hydrogen atom or an alkyl group having one to four carbon atoms, and R<22> 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.

Description

technical field [0001] The present invention relates to fluoropolymers and compositions for treating substrates (solid substrates such as paper and masonry). The invention also relates to a method of treating a substrate and a substrate to which the composition is attached. Background technique [0002] In the past, as a water and oil resistant processing agent for paper, the following processing agents have been proposed in the literature: (1) a processing agent containing a phosphoric acid ester compound having a polyfluoroalkyl group (hereinafter referred to as an Rf group) as an essential component (Japanese Patent Laid-Open Zhao No. 64-6196 communiqué, Japanese Unexamined Publication No. 3-123786); (2) a processing agent with a copolymer of acrylate, dimethylaminoalkyl methacrylate and vinyl acetate having an Rf group as an essential component (JP-A-7-206942 Gazette). [0003] As for the processing agent (1), since the phosphoric acid ester compound which has an Rf gr...
