Title (EN) METHODS AND COMPOSITIONS FOR INHIBITING VINYL AROMATIC MONOMER POLYMERIZATION
(FR) PROCÉDÉS ET COMPOSITIONS POUR INHIBER LA POLYMÉRISATION D'UN MONOMÈRE AROMATIQUE VINYLIQUE
Abstract: front page image
(EN)Methods and compositions are provided for inhibiting the polymerization of a vinyl aromatic monomer, such as styrene monomer, during elevated temperature processing thereof or during storage or shipment of polymer containing product. The compositions comprise a combination of a quinone methide derivative A) and a phenol compound B). The methods comprise adding from about 1-10,000 ppm of the combination to the monomer containing medium, per one million parts of the monomer.
(FR)L'invention concerne des procédés et des compositions pour inhiber la polymérisation d'un monomère aromatique vinylique, par exemple d'un monomère styrénique, pendant un traitement haute température ou pendant le stockage ou l'expédition d'un produit contenant des polymères. Les compositions selon l'invention comprennent une association d'un dérivé de quinone méthide A) et d'un composé phénol B). Les procédés selon l'invention comprennent l'étape consistant à ajouter entre approximativement 1 et 10.000 ppm de ladite association au milieu contenant le monomère, par million de part du monomère.
