ABS# Higher amounts (order of tenths of grams) of SIS, SISI, SISIS, SISISI and SISISIS (S is a
     polystyrene block, and I is a polyisoprene block) polystyrene-polyisoprene linear multiblock copolymers
     were prepared by sequential living anionic polymerization technique. In some cases the living ends of
     block copolymers were coupled with 1,2-dibromoethane, dichlorodimetilsilane or iodine. The
     polymerization reactions initiated by n-butyllithium were carried out in toluene solution. On these block
     copolymers, GPC and IR spectral analyses were performed, and the mechanical properties, including
     dynamic mechanical analysis were determined too.
