Problems solved by technology

[0009] However, for compounds with a perfluoroalkyl group having 6 or less carbon atoms, the orientation of the surface of the treated substrate is significantly reduced, and the melting point, glass transition temperature Tg, etc. are significantly lower than those of compounds with 8 carbon atoms, Therefore, it is seriously affected by environmental conditions such as temperature, humidity, stress, and exposure to organic solvents.
Therefore, the required sufficient performance cannot be obtained, and the durability and the like are also affected.

Embodiment

[0085] Next, the present invention will be described through examples.

Synthetic example 1

[0087] (1) Into a 1200ml autoclave equipped with a mixer and a thermometer

[0088] CF 3 (CF 2 ) 3 (CH 2 CF 2 )(CF 2 CF 2 )I (99.8GC%)

[0089] 603g (1.17 moles) and 7g of di-tert-butyl peroxide, and the autoclave was degassed with a vacuum pump. After heating the internal temperature to 80° C., ethylene was continuously introduced to adjust the internal pressure to 0.5 MPa. When the internal pressure decreased to 0.2 MPa, ethylene was introduced again so as to be 0.5 MPa, and the above operation was repeated. While maintaining the internal temperature at 80 to 115°C, 49 g (1.7 mol) of ethylene was introduced over about 3 hours. The content was recovered under the condition that the internal temperature was below 50°C to obtain 635g (98.9% yield) of

[0090] CF 3 (CF 2 ) 3 (CH 2 CF 2 )(CF 2 CF 2 )(CH 2 CH 2 )I (98.3GC%).

[0091] (2) In a three-necked flask with a capacity of 200 ml equipped with a condenser and a thermometer, add the

[0092] CF 3 (CF 2...

Synthetic example 2

[0102] (1) Used in the same manner as (1) in Synthesis Example 1

[0103] CF 3 (CF 2 ) 3 (CH 2 CF 2 )(CF 2 CF 2 ) 2 I (99.9GC%)

[0104] 529g (0.86 mol) and 5g of di-tert-butyl peroxide were introduced into the reaction of 34g (1.2 mol) of ethylene. As a result, 550g (yield 99.4%) of

[0105] CF 3 (CF 2 ) 3 (CH 2 CF 2 )(CF 2 CF 2 ) 2 (CH 2 CH 2 )I (99.1GC%).

[0106] (2) In a three-necked flask with a capacity of 200 ml equipped with a condenser and a thermometer, add the obtained in the above (4).

[0107] CF 3 (CF 2 ) 3 (CH 2 CF 2 )(CF 2 CF 2 ) 2 (CH 2 CH 2 )I (99.1GC%)

[0108] 150 g (0.24 mol) and 105 g (1.78 mol) of N-methylformamide were stirred at 150° C. for 5 hours. After completion of the reaction, the reaction mixture was washed with 40 ml of water, and the lower layer (132.3 g) was mixed with 135 g of a 15% by weight p-toluenesulfonic acid aqueous solution, and stirred at 80° C. for 7 hours. After the reaction mixture was left to st...

Abstract

Disclosed is a fluorine-containing copolymer comprising a copolymer of a polyfluoroalkyl alcohol (meth)acrylic acid derivative of formula [I] CnF2n+1(CH2CF2)a(CF2CF2)b(CH2CH2)cOCOCR=CH2 (wherein R is a hydrogen atom or a methyl group, n is an integer of 1 to 6, a is an integer of 1 to 4, b is an integer of 1 to 3, and c is an integer of 1 to 3) and a polysiloxane of formula [II] having a terminal (meth)acryloyloxy group (wherein R1 is a hydrogen atom or a methyl group, R2 is a C1-C6 straight-chain or branched alkylene group, R3 is a C1-C30 straight-chain or branched alkyl group, R4 and R5 are each a hydrogen atom, a methyl group, or a phenyl group, and m is an integer of 1 to 200).

Description

technical field [0001] The present invention relates to fluorine-containing copolymers. More specifically, it relates to a fluorinated copolymer that is effectively used as a surface treatment agent for powder and the like. Background technique [0002] The applicant has previously proposed a general formula containing 5 to 100% by weight [0003] C n f 2n+1 (CH 2 CF 2 ) a (CF 2 CF 2 ) b (CH 2 CH 2 ) c OCOCR=CH 2 [I] [0004] The shown polyfluoroalkyl alcohol (meth)acrylic acid derivative is a fluorine-containing polymer as a polymerized unit, and the organic solvent solution or aqueous dispersion of the fluorine-containing copolymer can be effectively used as, for example, a water- and oil-repellent agent, A surface modifying agent such as an oil barrier (see Patent Document 1). [0005] In addition, although fluorine-based oils such as perfluoropolyether oils have been used in combination with non-fluorine-based oils such as hydrocarbon oils and si...
