Title (EN) COATING POLYMERIZATION REACTORS WITH THE REACTION PRODUCTS OF THIODIPHENOLS AND A BLEACH
(FR) REVETEMENT DE REACTEURS DE POLYMERISATION AVEC LES PRODUITS DE REACTION DE THIODIPHENOLS ET UN AGENT DE BLANCHIMENT
Abstract: front page image
(EN)Polymerization reaction vessel having a coating on the inner surfaces thereof resulting from applying thereto an aqueous coating composition containing the reaction product of a thiodiphenol, or a derivative thereof, with a bleaching agent or material, such as, for example, sodium hypochlorite (NaOCl). When polymerizing olefinic monomers, such as vinyl halides, vinylidene halides, and vinylidene monomers having at least one terminal CH2=C < group, and mixtures therof, polymer buildup on the inner surfaces of the reaction vessel is substantially reduced. Multiple charges or batches of polymer can be made in said internally coated reaction vessel without opening the same between charges thus preventing the escape of unreacted monomer (s) to the surrounding atmosphere.
(FR)Conteneur de reaction de polymerisation ayant un revetement sur ses surfaces internes resultant de l"application d"une composition de revetement aqueuse contenant le produit de reaction d"un thiodiphenol, ou un derive de celui-ci, avec un agent ou un materiau de blanchiment tel que par exemple l"hypochlorite de sodium (NaOCl). En polymerisant des monomeres olefiniques tels que des halogenures de vinyle, des halogenures de vinylidene, et des monomeres de vinylidene ayant au moins un groupe terminal CH2=C<, et leur melange, le depot de polymere sur les surfaces internes du conteneur a reaction est sensiblement reduit. On peut effectuer de nombreuses charges de polymere dans ledit conteneur a reaction revetu interieurement sans l"ouvrir entre les charges, en evitant ainsi que le(s) monomere(s) qui n"ont pas reagi ne s"echappent dans l"atmosphere environnante.
