摘要

Polymeric foam flame retardants, processes to produce polymers of styrene expandable polymeric styrene foam or to produce extruded, and to produce foam polystyrene, and polymer of styrene expandable flame retardant.The inivenu00e7u00e3o relates to polymeric foams which comprise at least protected is a halogenated polymer, for example poliestirol brominated or block copolymer of estirol - butadiene, as an agent for protection of flame, having a bromine content in the range of 40 to 80% by weight, or comp. Love of tetrabromobisphenol A (TBBPA), to a method for its production.And the estirol expandable polymer protected flame.
