Problems solved by technology

[0012] When stearyl methacrylate was used, compared with when other esters were used or not used, the adhesive force was the same, and the peeling force at 25°C / 1 day and 70°C / 1 day was small, and The characteristic value of the contact angle to decane is large, but according to the additional test results of the present inventors, it is clear that even if the static contact angle before and after washing with water meets the requirements, the dynamic sliding angle after washing with hexadecane does not meet the requirements, and in the case of Metal rust resistance is not yet fully satisfied

[0055] [Solvent A]

[0056] Each of the above-mentioned components except the polymerization initiator was put into a reactor having a capacity of 500 ml including a condenser, and replaced with nitrogen for 30 minutes. Further, a polymerization initiator (500 g in total) was added stepwise to the reactor, the temperature in the reactor was gradually raised by 50° C., and a polymerization reaction was performed at this temperature for 23 hours while stirring.

Abstract

A fluorinated copolymer which is a copolymer of a polyfluoroalkyl alcohol (meth)acrylate represented by general formula [I]: CnF2n+1(CH2CF2)a(CF2CF2)b(CH2CH2)cOCOCR=CH2 (wherein R: a hydrogen atom ora methyl group; n: 1 to 6; a: 1 to 4; b: 1 to 3; c: 1 to 3), benzyl (meth)acrylate or styrene, and an Si group-containing crosslinkable (meth)acrylate represented by general formula [II]: CH2=CRCOO(CH2)dSi(OR1)eR2 3-e (wherein R: a hydrogen atom or a methyl group; R1 and R2: independently an alkyl group having 1 to 10 carbon atoms; d: 1 to 3; e: 1 to 3). A surface modifier containing the fluorinated copolymer as an active ingredient can exhibit an excellent dynamic sliding angle and excellent anti-corrosive properties after washing with hexadecane.

Description

technical field [0001] The present invention relates to a fluorine-containing copolymer and a surface modifier using it as an active ingredient. More specifically, it relates to a fluorinated copolymer excellent in rust resistance to metal, etc., and a surface modifying agent containing the same as an active ingredient. Background technique [0002] Patent Document 1 describes a release composition for adhesives, especially silicone-based adhesives, which contains the following monomers (1) to (3). Copolymers of monomer mixtures formed as active ingredients: [0003] (1) 50-99.5% by mass of general formula C n f 2n+1 (CH 2 CF 2 ) a (CF 2 CF 2 ) b (CH 2 CH 2 ) c OC OCR=CH 2 The indicated polyfluoroalkylvinyl monomer; [0004] R: hydrogen atom, methyl group [0005] n: an integer from 1 to 6 [0006] a: an integer from 1 to 4 [0007] b: an integer from 0 to 3 [0008] c: an integer from 1 to 3 [0009] (2) 0.5 to 50% by weight of an organic Si-based vinyl m...
