ABS# The mechanical properties of a brominated radial styrene-butadiene (SBS)
     and a linear styrene-isoprene (SIS) block copolymer are investigated as
     a function of bromination level. The brominated SBS has been investigated
     by dynamic mechanical analysis (DMA). The mechanical properties of
     brominated styrene diene block copolymers indicate that the central
     (polyisoprene or polybutadiene) soft block loses some elasticity
     becoming harder. On the other hand, the miscibility of polystyrene hard
     blocks with the central soft blocks increases with increasing degree of
     soft block bromination. Consequently, mainly the tensile strength and
     the true tensile strength decrease with increasing bromine content.
     Bromination affects the mechanical properties of the SIS material more
     than those of the SBS.
