FOAMED STYRENIC POLYMERS CONTAINING A BROMINATED STYRENE-BUTADIENE COPOLYMER AND HAVING ENHANCED CELL SIZE HOMOGENEITY

摘要

Extruded polymer foams are made from a polymer composition that includes an unbrominated styrenic polymer, a brominated vinyl aromatic/butadiene flame retardant, and an unbrominated vinyl aromatic/butadiene polymer. The unbrominated vinyl aromatic/butadiene polymer improves the cell homogeneity.
