Abstract: front page image
(EN)An oligomer of the formula (I) wherein G is an I; OH; OC(O)CH=CH2; OC(O)CCH3=CH2; OC(O)CCI=CH2; NRi H; N3; NCO; SQ wherein Q is H, alkyl, (CH2)nOH, (CH2)nNH2, (CH2)nOC(O)C(Me)=CH2, or (CH2)nNHC(O)C(Me)=CH2; SCN; COOH; SO3H; NHCOCH=CH2; NHCOC(CH3)=CH2); OC(O)NHCH2CH2OC(O)C(CHS)=CH2; or OC(O)NHCH2CH2OC(O)C(CHS)=CH2; subscript n is an integer from 1 to about 6, subscript x is an integer from 1 to about 6, subscripts y, z and m are each independently 1, 2 or 3, or a mixture thereof, the total number of carbons in said formula (I) excluding G ranges from about 8 to about 22, and a process for preparation thereof.
(FR)La présente invention concerne un oligomère de formule (I) : CnF2n+1 (CH2)X [(CF2CF2)y(CH2CH2)z]m G (I) dans laquelle G représente un I; OH; OC(O)CH=CH2; OC(O)CCH3=CH2; OC(O)CCI=CH2; NRi H; N3; NCO; SQ dans laquelle Q représente H, un alkyle, (CH2)nOH, (CH2)nNH2, (CH2)nOC(O)C(Me)=CH2, or (CH2)nNHC(O)C(Me)=CH2; SCN; COOH; SO3H; NHCOCH=CH2; NHCOC(CH3)=CH2); OC(O)NHCH2CH2OC(O)C(CHS)=CH2; ou OC(O)NHCH2CH2OC(O)C(CHS)=CH2; l'indice n représente un entier de 1 à environ 6, l'indice x représente un entier de 1 à environ 6, les indices y, z et m représentent chacun indépendamment 1, 2 ou 3, ou un mélange de ceux-ci, le nombre total de carbones dans ladite formule (I) à l'exception de G se trouve dans la plage allant d'environ 8 à environ 22. L'invention concerne également un procédé de préparation de celui-ci.
