Embodiment

[0175] Examples of the present invention are given below by way of illustration and not limitation.

Synthetic example 1

[0177] 150 g of tetrahydrofuran and 300 g of 1,3-bistrifluoromethylbenzene were charged into the reactor, and 160 ml of 0.7M allylmagnesium bromide was added dropwise thereto. Next, slowly add 300g (4.8×10 -2 mol) a compound of the following formula (I).

[0178]

[0179] The resulting solution was heated at 60 °C for 4 hours. It was then cooled to room temperature and added dropwise to 300 g of 1.2M aqueous hydrochloric acid to terminate the reaction. The lower layer or fluorine compound layer was recovered by separation operation and washed with acetone. The washed lower layer or fluorochemical layer is recovered again. The residual solvent was distilled off in vacuo to obtain 292 g of a fluoropolyether-containing polymer of the following formula (II).

[0180]

Embodiment 1

[0182] 200g (2.6×10 -2 mol) has the compound of formula (II) shown below, 200g 1,3-bis(trifluoromethyl)benzene, 12.7g (1.1×10 -1 mol) trimethoxysilane and 6.0×10 -1 g of chloroplatinic acid / vinylsiloxane complex (containing 1.6×10 -5 mol Pt) in toluene, mix them.

[0183]

[0184] The solution was aged at 80°C for 40 hours. The solvent and unreacted reactants were then distilled off in vacuo. The remaining low-boiling and high-boiling fractions were subsequently removed, still by molecular distillation, to obtain 100 g of liquid product.

[0185] Through NMR analysis, it was determined that the product had the structure of the following formula (III).

[0186]

Abstract

A fluoropolyether-containing polymer-modified silane having (1) is provided wherein Rf is a fluorooxyalkyl or fluorooxyalkylene-containing polymer residue, Y is a divalent to hexavalent hydrocarbon group, R is C 1 -C 4 alkyl or phenyl, X is a hydrolysable group, n is an integer of 1 to 3, m is an integer of 1 to 5, and ± is 1 or 2. A surface treating agent comprising the silane or partial hydrolytic condensate thereof cures under mild conditions into a water / oil repellent layer having abrasion resistance, weatherability and low dynamic friction.

Description

[0001] Cross References to Related Applications [0002] This nonprovisional application claims priority under 35 U.S.C. §119(a) to Patent Applications Nos. 2014-074213 and 2014-250460 filed in Japan on March 31, 2014, and December 11, 2014, respectively, which The entire contents are incorporated herein by reference. technical field [0003] The present invention relates to silanes modified with fluoropolyether-containing polymers, and more particularly to fluoropolyether-containing polymer-modified silanes capable of forming coatings that are water, oil and weather resistant, including modified silanes and A surface treatment agent of / or its partial hydrolysis condensate, and articles treated with the surface treatment agent. Background technique [0004] Recently, the need to install touch panels as screens on mobile phones and other displays has accelerated. While the touchpad has a screen that remains exposed, there are plenty of opportunities for your finger or cheek...
