Beschreibung
Zusammenfassung:	A flowable dispersion at room temperature of syndiotactic polybutadiene particles in an aqueous mixture that includes at least one emulsifier. The dispersion reduces the need for temperature control equipment for storing or transferring the dispersion during processing. The syndiotactic polybutadiene particles in the dispersion are formed from a syndiotactic polybutadiene cement including hydrocarbon solvents resulting from a polymerization process that are subsequently removed from the dispersion by evaporation. L'invention concerne une dispersion fluide à température ambiante de particules de polybutadiène syndiotactique dans un mélange aqueux qui comprend au moins un émulsifiant. La dispersion réduit le besoin d'un équipement de régulation de température pour stocker ou transférer la dispersion pendant le traitement. Les particules de polybutadiène syndiotactiques dans la dispersion sont formées à partir d'un ciment de polybutadiène syndiotactique comprenant des solvants hydrocarbonés résultant d'un processus de polymérisation lesquels sont ensuite éliminés de la dispersion par évaporation.
