BROMINATED BUTADIENE/VINYL AROMATIC COPOLYMERS, BLENDS OF SUCH COPOLYMERS WITH A VINYL AROMATIC POLYMER, AND POLYMERIC FOAMS FORMED FROM SUCH BLENDS

摘要

A thermally stable brominated butadiene copolymer, such as brominated styrene/butadiene block copolymer, brominated random styrene/butadiene copolymer or brominated styrene/butadiene graft copolymer, preparation of the brominated butadiene copolymers, use of the brominated butadiene copolymers as a flame retardant additive and polymeric compositions, both foamed and non-foamed, that incorporate a flame-retarding amount of brominated butadiene copolymer.
