Fluorinated imides useful for imparting repellency of low surface tension fluids to thermoplastic polymers of formulae (A), (B), (C), (D) and (E) wherein R1 is F(CF2)x-(CH2)m, or F(CF2)xSO2N(R5)(CH2)p wherein x is from about 4 to about 20, m is from about 2 to about 6, p is from 1 to about 12, and R5 is an alkyl radical of from 1 to about 4 carbons; R2 is a linear, branched or cyclic alkylene or poly(oxyalkylene) hydrocarbon group having from about 2 to about 15 carbons; R3 is selected from the group consisting of F(CF2)x-(CH2)m, F(CF2)x-(CH2)m-OC(O)-(CH2)n, and F(CF2)xSO2N(R5)(CH2)pOC(O)(CH2)n wherein x is from about 4 to about 20, m is from about 2 to about 6, n is from about 2 to about 12, p is from 1 to about 12, and R5 is an alkyl radical of from 1 to about 4 carbons; R4 is an alkyl or alkenyl group of from about 4 to about 20 carbons, and R6 is a linear or branched alkyl having from about 4 to about 20 carbons.
La présente invention concerne des imides fluorés permettant de conférer un caractère répulsif des fluides de faible tension superficielle à des polymères thermoplastiques représentés par les formules générales (A, B, C, D et E). Dans ces formules, R¿1? représente F(CF¿2?)¿x?-(CH¿2?)¿m?, ou F(CF¿2?)¿x?SO¿2?N(R¿5?) (CH¿2?)¿p? dans lesquels x vaut d'environ 4 à environ 20, m d'environ 2 à environ 6, et p d'environ 1 à environ 12, R¿5? étant un radical alkyle portant de 1 à environ 4 atomes de carbone. R¿2? est un groupe linéaire, ramifié ou cyclique alkylène ou poly(oxyalkylène) hydrocarbure portant d'environ 2 à environ 15 atomes de carbone. R¿3? appartient au groupe des F(CF¿2?)¿x?-(CH¿2?)¿m?, F(CF¿2?)¿x?- (CH¿2?)¿m?-OC(O) - (CH¿2?)¿n?, et F(CF¿2?)¿x?SO¿2?N(R¿5?) (CH¿2?)¿p?OC(O) (CH¿2?)¿n? dans lequel x vaut d'environ 2 à environ 12, p vaut de 1 à environ 12, et R¿5? est un radical alkyle portant de 1 à environ 4 atomes de carbone. R¿4? est un groupe alkyle ou alcényle portant d'environ 4 à environ 20 atomes de carbone, et R¿6? est un alkyle linéaire ou ramifié portant d'environ 4 à environ 20 atomes de carbone.
