Abstract

L'adjonction à des polystyrènes à résistance élevée aux impacts de quantités efficaces de polystyrènes bromés à faible poids moléculaire permet d'obtenir de manière inattendue une bonne rétention des propriétés des polystyrènes en même temps qu'une propriété ignifuge voulue, par exemple UL-94 VO. Par contraste, des polymères de styrène bromé de poids moléculaire élevé (ayant un degré de polymérisation égal à 2000) ne transmettent pas à des polystyrènes à résistance élevée aux impacts une bonne qualité de rétention de propriétés telles que la résistance aux impacts et la dureté. Le degré de polymérisation des polystyrènes bromés décrits est généralement compris entre 3 et 20 environ et leur halogénation peut varier considérablement. Ces polystyrènes à résistance élevée aux impacts, mélangés à ces polystyrènes bromés à faible poids moléculaire, peuvent être aisément traités par des équipements classiques.
