The structure and properties of block copolymers (BCPs) of styrene and butadiene of grade StiroTEP-70 (styrene:butadiene = 70:30, Mw/Mn = 1.43–1.45) are discussed. Analysis of IR spectra enables the BCP to be treated as polystyrene-stat-copoly(butadiene/styrene/1,2-butadiene)-polystyrene. It is suggested that the absorption band at 542 cm-1 be considered as characteristic when identifying polymers with extensive polystyrene phases. At temperatures of 190–230°C, the BCP is partially crosslinked, and at 260°C it breaks down. The BCP is processed well at temperatures up to 200°C.
