METHOD OF SURFACE MODIFICATION OF CONTACTING STRUCTURAL MEMBERS AND MEDIA Russian patent published in 2003 - IPC

FIELD: organic chemistry. SUBSTANCE: invention describes method of surface modification of contacting structural members and media involving the use of organofluoric substances. Derivatives of isobutane are used as organofluoric substances comprising fluoro- containing organic substituents of the general formula: Hal-C-[C(R₁)_n(R₂)_m(OR₃)_p]₂ CF(OR₁)₁ (OR₃)_q, where Hal is F, Cl, Br, J,H; R₁ means -OCH₂(CF₂CF₁)_kH, -OC_kH2_k+1; R₂ means ; R₃ means where n = 0-3; m = 0-3; p = 0-3; l = 0-2; q = 0-2; k = 1-8; or methane tricarboxylic acid nonaesters of non-symmetric structure of the general formula: Hal-C-[CR₁R₂R₃)(CR₁R₂R₃)C(R₁R₂R₃)], where Hal is F, Cl, Br, J, H; R₁ = R₂ = R₃ mean where n = 1-8 under condition that at least one R differs from others; or derivatives of fluorinated esters of fluoroolefins and alcohols of the general formula: R_fC(H_2-nHal_k)OR where R_f means (C_mH_2m-pHal_p)H; R means (CH₂)₁H, C(CH₃)_kH_3-k; Hal is F, Cl where n = 1, 2; m = 1-3; p = 1-2; l = 1-4; k = 2, 3 or their mixture. Method is designated for application in technical systems working under condition of dry friction or depleted lubrication, for treatment of cutting and stamp tool, saturation of polymer media with functional filling agents with simultaneous providing casting or extrusion possibility. EFFECT: improved method of modification, valuable properties of compounds. 4 cl
