example

[0103] Hereinafter, although an example and a comparative example are shown and this invention is demonstrated in more detail, this invention is not limited to the following example.

example 1

[0105] (i) 500 g of the polymer represented by the following formula

[0106] [chemical 18]

[0107] HOOC-CF 2 -(OC 2 f 4 ) p (OCF 2 ) q -OCF 2 COOH

[0108] (p / q=0.9, )

[0109] It was dissolved in a mixed solvent of 400 g of 1,3-bis(trifluoromethyl)benzene and 100 g of tetrahydrofuran, and 80 g of a 40% toluene solution of bis(2-methoxyethoxy)aluminum sodium hydride was added dropwise. After stirring at room temperature for 3 hours, an appropriate amount of hydrochloric acid was added, and the mixture was thoroughly stirred and washed with water. Further, the lower layer was taken out, and the solvent was distilled off to obtain 440 g of a liquid product. pass 19 F-NMR confirmed that the obtained product was a mixture containing the following (4a) 50 mol%, (4b) 48 mol%, and (4c) 2 mol%.

example 2

[0135] 30 g of the mixture obtained in the step (iii) was dissolved in 20 g of 1,3-bis(trifluoromethyl)benzene, and 0.10 g of a toluene solution of platinum chloride / vinylsiloxane complex was added dropwise ( Contains 2.5 x 10 -8 moles of Pt monomer), and 2.5 g of a 1:1 addition reaction product (HM-VMS) of tetramethyldisiloxane (HM) and vinyltrimethoxysilane (VMS), aged at 90°C for 2 Hour. Then, the solvent and unreacted substances were evaporated under reduced pressure to obtain 30 g of a liquid product.

[0136] In addition, the HM-VMS was prepared using the following method.

[0137] 40 g of tetramethyldisiloxane (HM) and 40 g of toluene were mixed, and heated to 80°C. Slowly add 44.2g of vinyltrimethoxysilane (VMS) and 2g of toluene solution of chloroplatinic acid / vinylsiloxane complex (containing 1.1×10 -7 moles of Pt monomer). The resulting mixture was purified by distillation to obtain 84 g of a 1:1 addition reaction product (HM-VMS) shown below.

Abstract

A fluorooxyalkylene group-containing polymer composition comprising a liner fluorooxyalkylene group-containing polymer represented by the formula (1) which has a hydrolysable group at a terminal and is hereinafter called one-terminal hydrolyzable polymer, and a liner fluorooxyalkylene group-containing polymer represented by the formula (2) which has hydrolysable groups at both terminals and is hereinafter called "both-terminal hydrolyzable polymer", wherein the amount of the both-terminal hydrolyzable polymer is 0.1 mole % or more but less than 10 mole %, relative to the total mole of the one-terminal hydrolyzable polymer and the both-terminal hydrolyzable polymer.

Description

technical field [0001] The present invention relates to a polymer composition containing a fluorine oxyalkylene group. Specifically, the present invention relates to a polymer composition that has excellent adhesion to substrates, water and oil repellency, low dynamic friction, and excellent scratch resistance. A film-coated polymer composition containing a fluorine oxyalkylene group, a surface treatment agent containing the composition, and an article treated with the surface treatment agent. Background technique [0002] In recent years, in order to improve the appearance and visibility, there has been an increasing demand for technology that prevents fingerprints from adhering to the surface of the display or technology that makes dirt fall off easily, and the development of materials that can meet these needs has been desired. Especially on the surface of a touch panel display, it is desirable to provide a water- and oil-repellent layer because fingerprints and dirt tend...
