Title (EN) FLUORINATED DIOL BASED POLYURETHANE ACRYLATE OR VINYL TYPE MATERIAL FOR COVERING AN OPTICAL FIBRE
(FR) MATERIAU POLYMERE DE TYPE POLYURETHANNE ACRYLATE OU VINYLIQUE POUR REVETEMENT DE FIBRE OPTIQUE A BASE D'UN DIOL FLUORE
Abstract: front page image
(EN)The invention relates to a fluorinated diol based polyurethane acrylate or vinyl type material for covering an optical fibre, said diol having formula (I): C¿n?F¿2n+1?-A-CH¿2?OCH¿2?-C(CH¿2?OH)¿2?-R wherein n is 2-20 and A represents -CH=CH- or -CH¿2?CH¿2?- and R is an alkyl group containing 1 - 4 carbon atoms. The invention also relates to a fibre covered with this photo-cross-linked polymer and a fibre-drawing method comprising a stage in which the fibre is coated with the inventive material.
(FR)L'invention a pour objet un matériau polymère de type polyuréthanne acrylate ou vinylique pour revêtement de fibre optique à base d'un diol fluoré, ce diol présentant la formule (I): C¿n?F¿2n+1?-A-CH¿2?OCH¿2?-C(CH¿2?OH)¿2?-R dans laquelle n vaut de 2 à 20 et A signifie -CH=CH- ou -CH¿2?CH¿2?- et R est un groupe alkyle contenant 1 à 4 atomes de carbone. L'invention a aussi pour objet une fibre revêtue de ce polymère photoréticulé, et un procédé de fibrage comprenant l'étape d'enduction de la fibre avec un matériau selon l'invention.
