Abstract

Controlled cyclization of styrene-butadiene rubber (SBR) was achieved with the aid of cationic catalyst system based on diethylaluminium chloride (AlEt₂Cl) and benzyl chloride (C₆H₅CH₂Cl) and by working in xylene solution at high temperature (T > 100°C). The main parameters of the cyclization process were investigated. Elastomers with low intrinsic viscosity, ready solubility, free gel were obtained. The products were characterized with IR ¹H-NMR, DSC, GPC. The polycyclic structure was determined.
