Title

(FR) (CO)POLYMÈRE CONTENANT DES DIÈNES MODIFIÉS, SON PROCÉDÉ DE PRÉPARATION ET SON UTILISATION EN TANT QUE RETARDATEUR DE FLAMME
Abstract
(EN)
The invention relates to the field of modified diene-containing (co)polymers, in particular, modified styrene-butadiene copolymer, which can be used as flame retardants for expandable polystyrene polymer compositions. In particular, the invention relates to a modified diene-containing (co)polymer, a method for preparing it, and use as a flame retardant for expandable polystyrene. The modified diene-containing (co)polymer claimed in the invention is characterized by high thermostability, namely, a 5% weight loss temperature of at least 180°C, a molecular weight of at least 1500 g/mol and a halogen content of at least 35 wt.%; the content of tertiary and/or allyl halogenides is in the range from 0 to less than 1.5 wt.%, and also does not affect the polymerization process and the formation of polystyrene granules either, and allows to obtain polystyrene granules with a yellowness index of 2 to 6 units, comparable to the yellowness index of polystyrene granules containing HBCD (from 0 to 3 units).
(FR)
La présente invention concerne le domaine des (co)polymères contenant des diènes modifiés, en particulier, un copolymère styrène-butadiène modifiés, qui peuvent être utilisés en tant que retardateurs de flamme pour des compositions de polymère de polystyrène expansé. En particulier, l'invention concerne un (co)polymère contenant des diènes modifiés, un procédé de préparation de celui-ci et son utilisation en tant que retardateur de flamme pour le polystyrène expansé. Le (co)polymère contenant des diènes modifiés selon l'invention se caractérise par une thermostabilité élevée, à savoir une température de perte de poids à 5% d'au moins 180°C, un poids moléculaire d'au moins 1500 g/mol et une teneur en halogène d'au moins 35% en poids ; la teneur en halogénures tertiaires et/ou allyliques est comprise dans la plage de 0 à moins de 1,5% en poids, et ne modifie pas le processus de polymérisation et la formation de granulés de polystyrène, et permet d'obtenir des granulés de polystyrène ayant un indice de jaunissement de 2 à 6 unités, comparables à l'indice de Jaunissement de granulés de polystyrène contenant du HBCD (de 0 à 3 unités).
