ABSTRACT Thiol-ene modification of high vinyl content thermoplastic elastomeric styrene butadiene styrene (SBS) block copolymer (BCP) was carried out using different thiolating agents in toluene at 70 °C. 1H NMR analysis confirmed the participation of vinyl double bond in the thiol-ene modification reaction of SBS. Surface morphology of the block copolymers evaluated by atomic force microscopy analysis showed higher roughness after the thiol-ene reaction. The thiol-modified SBS block copolymer showed better adhesion strength and oil resistance properties than the pristine SBS.

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.
