Title (EN) HALOBUTYL ELASTOMERS
(FR) ÉLASTOMÈRES HALOGÉNOBUTYLE
Abstract: front page image
(EN)The present invention relates to the modification of butyl elastomers, particularly halobutyl elastomers, under solvent free conditions with a phase transfer catalyst, particularly tetrabutyammonium bromide or trioctylmethylammonium chloride, in the presence of an alkyl metal salt of an oxygen or sulfur-based nucleophile. Suitable nucleophiles for use in the present invention include metal salts of tert-butylacetic acid, stearic acid, benzoic acid, 4-(dimethylamino)benzoic acid, antrancene-9- carboxylic acid, linoleic acid or mixture thereof, which are prepared by neutralization with an appropriate hydroxide base.
(FR)La présente invention concerne la modification d’élastomères de type butyle, en particulier d’élastomères halogénobutyle, dans des conditions sans solvant avec un catalyseur de transfert de phase, en particulier le bromure de tétrabutylammonium ou le chlorure de trioctylméthylammonium, en présence d'un sel d’alkylmétal d'un nucléophile à base d’oxygène ou de soufre. Les nucléophiles appropriés pour un usage dans la présente invention comprennent des sels métalliques d'acide tert-butylacétique, d'acide stéarique, d'acide benzoïque, d'acide 4-(diméthylamino)benzoïque, d'acide antrancène-9-carboxylique, d'acide linoléique ou de leur mélange, lesquels sont préparés par neutralisation avec une base appropriée de type hydroxyde.
