Embodiment 1）

[0147] Into the reaction vessel, a mixture comprising (6a) 60%, (6b) 2% and (6c) 38% represented by the above formula (terminal-CF 3(68% of the total terminal groups in the mixture) 75g, 50g of 1,3 trifluorotoluene and 15g of tetrahydrofuran are dissolved in a mixed solvent, and bis(2-methoxyethoxy)sodium aluminum hydride is added dropwise 40% toluene solution 38g. After stirring at room temperature for 3 hours, an appropriate amount of hydrochloric acid was added, stirred well, and washed with water. Furthermore, the lower layer was taken out, and after distilling off the solvent, a part of the product mixture [mainly (6c) component] was further distilled off under reduced pressure to obtain 40 g of a liquid product. use 19 F-NMR, confirmed that in the mixture of the obtained products, the end-CF 3 The ratio of the group to the total terminal group was 65%, and it was confirmed that it contained a mixture of the following (7a), (7b) and (7c).

Embodiment 2）

[0165] 40g of the mixture containing (8a), (8b) and (8c), 140g of 1,3 trifluorotoluene, 20g of 1,4-bis(dimethylsilyl)benzene, chloroplatinic acid / vinylsiloxane 0.01g toluene solution of alkane complex (containing 2.5×10 Pt monomer -9 mol) were mixed and aged at 80°C for 3 hours. After the solvent was distilled off under reduced pressure, the separated polymer layer (lower layer) was recovered, washed with acetone, and then concentrated under reduced pressure to obtain 30 g of a liquid product. The obtained product was a mixture containing (11a), (11b) and (11c) represented by the following formula.

[0167] 25g of the mixture containing the above (11a), (11b) and (11c), 25g of 1,3 trifluorotoluene, 1.1g of vinyltrimethoxysilane (VMS), chloroplatinic acid / vinylsiloxane complex 0.01 g of toluene solution (containing Pt monomer 2.5 x 10 -9 mol) were mixed and aged at 80°C for 3 hours. Then, the solvent and unreacted substances were distilled off under reduced pres...

Embodiment 1

[0173] About Example 1, except having used 1.1 g of octenyltrimethoxysilanes instead of 0.7 g of alkenyltrimethoxysilanes, it synthesize|combined by operation similar to Example 1. The resulting product is a mixture comprising (13a), (13b) and (13c) represented by the following formula, terminal-CF 3 The proportion of the bases relative to the total end groups in the mixture was 65% (composition 3).

Abstract

There is disclosed a fluorooxyalkylene group-containing polymer composition represented by the following average composition formula (1). In the formula, the ratio of the Rf 2 group is 30 to 75 mole%, relative to a total of all of the terminal groups in the composition, and the fluorooxyalkylene group-containing polymer composition includes a one-terminal hydrolyzable silyl group-containing polymer and a both-terminal hydrolyzable silyl group-containing polymer, A-Rf 1 -B (1) wherein Rf 1 represents a divalent linear fluorooxyalkylene group, A and B represent groups represented by an Rf 2 group or a group represented by the formula (2), Z represents a divalent to heptavalent linking group having a silalkylene structure or a silarylene structure but no siloxane bond, X represents a hydrolyzable group, and Y is a linking group represented by C c H 2c or C 2 H 4 -C r F 2r -C 2 H 4 . As a result, there is provided a fluorooxyalkylene group-containing polymer composition of forming a coated film which is excellent in water- and oil-repellency, low dynamic friction coefficient, releasing property, property of wiping off stain and excellent in abrasion resistance, adhesiveness to a substrate and alkaline resistance, and to provide a surface treatment agent, an article and an optical article.A-Rf1-B (1).

Description

technical field [0001] The present invention relates to a fluorine-containing oxyalkylene (fluorooxyalkylene) polymer composition, a surface treatment agent containing the composition, articles and optical articles treated with the surface treatment agent. Background technique [0002] Generally, the perfluorooxyalkylene group-containing compound has very small surface free energy, so it has water and oil repellency, chemical resistance, lubricity, mold release property, antifouling property and the like. Taking advantage of these properties, it is widely used in industry as waterproof, oil-proof, and antifouling agents for paper and fibers, lubricants for magnetic recording media, oil-repellent agents for precision machines, mold release agents, cosmetic raw materials, and protective films. [0003] However, these properties also mean that there is no adhesiveness or adhesion to other substrates, and even if it can be coated on the surface of the substrate, it is difficult ...
