Изобретение относится к полисульфидному вулканизационному составу, находящему применение как защитное покрытие поверхностей, в качестве изолятора в дорожном и жилищном строительстве и др. Цель изобретения состоит в получении полисульфидного состава и вулканизата с высокими техническими и экологическими показателями при использовании ингредиентов с пониженным меркаптанным запахом токсичностью, при степени и скорости вулканизации, не зависящими от условий окружающей среды. Поставленная цель достигается путем приготовления состава, содержащего полисульфидный полимер и/или сополимер с мол. м. 2000 - 200000, содержание SH- и/или SSH-групп 0 - 1 мол/кг, со средней степенью полимульфидности 2,20 - 4,00, степенью разветвленности 0 - 4 мол. %, степенью полимеризации 10 - 500, в количестве 90 - 110 мас.ч. Общая формула приведена в описании.The invention relates to a polysulfide curing composition, which is used as a protective coating of surfaces, as an insulator in road and housing, etc. degrees and rates of vulcanization independent of environmental conditions. This goal is achieved by preparing a composition containing a polysulfide polymer and / or copolymer with mol. m. 2000 - 200000, the content of SH - and / or SSH-groups 0 - 1 mol / kg, with an average degree of polymulphide 2.20 - 4.00, the degree of branching 0 - 4 mol. %, the degree of polymerization of 10 to 500, in an amount of 90 to 110 parts by weight The general formula is given in the description.
