Abstract Anionically prepared block copolymers of butadiene and styrene exhibit solution properties which result from a two dimensional ordering of the polymer molecules. The most notable of these properties is the iridescent colors of toluene solutions which are dependent on concentration and abruptly change on mechanical deformation. Electron micrographs of the surface of cast films indicate that the ordered structure is retained to some degree in the solid state.

This work presents the results of optimization compositions of polymer-modified binder (PMB) by a compromise task. The conducted study of influence two prescription factors – containing styrene-butadiene-styrene and sulfur – on which is a set of indicators of polymer-bitumen binders were carried out. The regularities of these factors of mutual influence were established by such indicators as the Fraas brittleness temperature, penetration, softening point, ductility. The dosages of SBS and sulfur have been determined by ensuring the achievement of the required level of PBB indicators in accordance with GOST R 52056-2003 «Bitumen-polymer road binders are based on styrene-butadiene-styrene block copolymers.

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.
