Embodiment

[0294] Hereinafter, synthesis examples, examples, reference examples, and comparative examples are shown, and the present invention will be described in more detail, but the present invention is not limited by the following examples.

[0295] Examples and comparative examples used the compounds obtained in the following synthesis examples.

Synthetic example 1

[0296] [Synthesis Example 1] Synthesis of Compound 1

[0297] 150 g of tetrahydrofuran and 300 g of 1,3-bis(trifluoromethyl)benzene were mixed in a reaction vessel, and 160 ml of 0.7 M allylmagnesium bromide was added dropwise. Then, slowly drop into the following formula (A)

[0298] [Chemical 55]

[0299]

[0300] Represented compound 200g (4.8×10 -2 mol), heated at 60°C for 4 hours. After heating, it was cooled to room temperature, and the solution was dropped into 300 g of a 1.2M hydrochloric acid aqueous solution to stop the reaction. After recovering the fluorine compound layer as the lower layer by a liquid separation operation, it was washed with acetone. The fluorine compound layer as the lower layer after washing was recovered again, and the remaining solvent was distilled off under reduced pressure to obtain the following formula (B):

Abstract

The present invention provides a resin product surface-treated with a surface-treating agent that can form a water- and oil-repellent layer excellent in abrasion resistance in a short period of time, especially under curing conditions such as curing at room temperature on the surface of the resin. Polymer-modified silanes containing fluoropolyether groups and / or their partially hydrolyzed condensates. A surface treatment agent is used, which comprises the following formula (1) [Rf is a 1- or 2-valent polymer residue containing a fluoropolyether group, Y is a siloxane bond, a silylene structure or a silylene A 2-6 valent hydrocarbon group with a base structure, R is an alkyl group or a phenyl group, X is a hydrolyzable group, n is 1-3, m is 1-5, Z is a hydrogen atom or by ‑SiR' (3‑a) X' a ‑W‑(SiR (3‑n) x n ) b AA (R' is the same as R, X' is the same as X, W is the same as Y, a is 0-3, b is 1-5, E is a monovalent organic group), α is 1 or 2] The indicated polymer-modified silanes containing fluoropolyether groups and / or their partial hydrolysis condensates.

Description

technical field [0001] The present invention relates to a polymer-modified silane containing fluoropolyether groups and a resin article surface-treated with a surface treatment agent containing the silane and / or its partial hydrolysis condensate. Background technique [0002] In recent years, touch panelization of screens has been accelerated, including displays for mobile phones. However, the touch panel is in a state where the screen is exposed, and there are many chances of direct adhesion of fingers, cheeks, etc., and dirt such as sebum is easy to adhere to, which has become a problem. Therefore, in order to improve the appearance and visibility, there is an increasing demand for technology to make the surface of the display less prone to fingerprints and technology to make it easier to remove dirt, and the development of materials that can meet these needs is desired. In particular, it is desirable to provide a water- and oil-repellent layer on the surface of a touch p...
