FIELD: chemistry.
SUBSTANCE: invention relates to substantially free from ETU cross-linkable compositions based on chloroprene rubber, to a method of producing vulcanizates from such compositions and to vulcanised rubber obtained using said method. Cross-linkable composition contains chloroprene rubber, a cross-linking agent and a vulcanization accelerator selected from N-methylthiazolidine-2-thione. Chloroprene rubber contains metal cations from the second or third main group in amount of more than 0.25 wt % and resinate anions in amount of more than 2.5 wt % and less than 4.5 wt % based on total amount of chloroprene rubber.
EFFECT: technical result of invention consists in development of cross-linkable compositions essentially free from ETU containing chloroprene rubber, which have reduced vulcanization time and enable the accelerated process of obtaining vulcanizate, preferably without detriment to the vulcanization resistance.
