Embodiment

[0564] The surface treatment agent of the present invention will be specifically described by the following examples, but the present invention is not limited to these examples.

Synthetic example

[0566] The fluorine-containing silicon-containing polymer of the present invention was synthesized according to the following scheme.

[0567]

[0568] [where, PFPE represents CF 3 CF 2 CF 2 O(CF 2 CF 2 CF 2 O) y CF 2 CF 2 -base (here, y is an integer of 10-50), m is an integer of 3-40, and n is an integer of 50-200. ]

Synthetic example 1

[0569] Synthesis Example 1 (Step a): Synthesis of 2-[3-poly(perfluoropropyloxy)-2,2,3,3-tetrafluoropropoxy]ethoxyvinyl ether

[0570]

[0571] In a 1L eggplant-shaped flask, add the following structural formula: PFPE-CH 2 60 g (15 mmol) of perfluoropolyether-based alcohol represented by OH (Demnum SA (number average molecular weight 4000), Daikin Industries, Ltd.), 3.5 g (103 mmol) of tetrabutylammonium hydrogensulfate, 40% aqueous sodium hydroxide solution 120 mL and 250 mL of m-hexafluoroxylene, stirred at room temperature for 30 minutes under a nitrogen atmosphere. 120 mL of 2-chloroethyl vinyl ether was added to the above mixture, a Dimroth condenser was attached to the eggplant-shaped flask, and the mixture was stirred at 70° C. for 48 hours under a nitrogen atmosphere. After cooling, the reaction solution was distilled off the solvent with an evaporator until it was almost completely dry. The remaining reactants were dissolved in a fluorine-based inert liquid (Fluor...

Abstract

Provided is a fluorine-containing, silicon-containing polymer which is useful in forming a surface treatment layer that has water repellency, oil repellency, and antifouling properties, and has excellent surface lubricity. At least one type of fluorine-containing, silicon-containing polymer shown in general formulas (A) and (B) (wherein, each symbol is as defined in the description).

Description

technical field [0001] The present invention relates to fluorine-containing silicon-containing polymers and surface treatment agents containing such polymers. Background technique [0002] It is known that certain fluorine-containing compounds can provide excellent water repellency, oil repellency, stain resistance, etc. when used for surface treatment of substrates. A layer obtained from a surface treatment agent containing a fluorine-containing compound can be applied as a so-called functional film to various substrates such as glass, plastics, fibers, building materials, and the like. [0003] In the prior art, especially in the application of optical components, substrates made of inorganic glass are used. In order to prevent the adhesion of dirt such as fingerprints, as an antifouling coating, fluorine-containing compound layer. As such a fluorine-containing compound, a surface treatment agent containing a fluorine-containing silane compound having a perfluoropolyethe...
