FIELD: chemistry.
SUBSTANCE: invention relates to sulphur-containing polymer, which is applied as plasticiser, as well as to vulcanising composition. Sulphur polymer has terminal halogen groups and is presented by the following formula: X-(R-Sr)n-R-X, where R represents alkyl group, containing bond -O-CH2-O-, and has from 3 to 26 carbon atoms, X represents halogen atom, n stands for integer number from 1 to 200 and r has average value 1 or more and less than 2. Vulcanising composition contains said sulphur-containing polymer, polysulphide polymer and vulcanising agent.
EFFECT: invention makes it possible to obtain sulphur-containing polymer with high plasticising ability and heat resistance, low temperature of vitrification.
