Title (EN) PERFLUOROETHER-CONTAINING FLUOROELASTOMERS WITH GOOD LOW TEMPERATURE CHARACTERISTICS
(FR) FLUOROELASTOMERES CONTENANT DES PERFLUOROETHERS ET PRESENTANT DE BONNES CARACTERISTIQUES A BASSE TEMPERATURE
Abstract:
(EN) The present invention provides a process of curing a fluorocarbon elastomeric composition comprising: providing a mixture of a saturated elastomeric gum comprising repeating interpolymerized units derived from vinylidene fluoride and a perfluorinated ether of the formula CF2=CF(CF2)m-O-R$i(f) wherein m = 1-4, R$i(f) is aperfluorinated aliphatic group optionally containing O atoms, at least one crosslinking agent, and an acid acceptor, shaping the mixture; and curing the resulting shaped article.
(FR) La présente invention concerne un procédé de durcissage de composition élastomère de fluorocarbone. Ce procédé consiste à prendre un mélange entre, d'une part une gomme élastomère saturée comprenant une répétition d'unités interpolymérisées issues d'un vinyldiène fluorure et d'un éther perfluoré de formule CF2=CF(CF2)m-O-R$i(f) (où m = 1-4 et où R$i(f) est un groupe aliphatique perfluoré portant éventuellement des atomes d'oxygène), d'autre part un agent de réticulation et enfin d'un accepteur d'acide. Le procédé consiste ensuite à mettre en forme le mélange et à faire durcir l'article formé résultant.
