FIELD: chemistry. ^ SUBSTANCE: invention relates to moulded elastomer articles made from a vulcanised composition of elastomer latex. Described is a vulcanised aqueous composition of synthetic latex rubber, which contains latex rubber, a vulcanising agent, an activator and an accelerator composition for synthetic latex rubber. The accelerator is obtained from a conjugated diane and, possibly, vinylaromatic copolymer and contains: (i) diethyl dithiocarbamate and (ii) diphenyl guanidine and does not contain any thiazole compounds. Weight ratio of components (i) and (ii) lies between 0.80 and 2.00. Described also is a method of making articles from the aqueous composition of synthetic latex. The method involves preparation of a latex dispersion or emulsion, holding the latex dispersion for up to 8 days, loading forms in form of an article into latex and vulcanisation of the latex present in that form. ^ EFFECT: cheap method based on water without the need for using novel expensive materials or equipment, use of smaller amounts of vulcanising agents and stabilisers. ^ 10 cl, 1 tbl, 1 ex |
