Zusammenfassung:FIELD: chemistry. ^ SUBSTANCE: invention relates to low-molecular ternary copolymers of ethylene, perfluorinated olefin and perfluoroallyl fluorosulphate as the third monomer, of general formula: , where Rf=-CF3, -OCF2CF2CF3, l=20.4-26.9, m=10.8-16.1, n=3.7-6.2 with number-average molecular weight 4300-5700. ^ EFFECT: obtaining low-molecular ternary copolymers of ethylene, having high fluidity at different temperatures, based on which, in the absence of a solvent, cold setting sealants with high stability in polar solvents and alkaline media can be obtained. ^ 1 cl, 3 ex, 1 tbl Изобретение имеет отношение к низкомолекулярным тройным сополимерам этилена, перфторированного олефина и перфтораллилфторсульфата в качестве третьего мономера общей формулы: ! , ! где Rf=-CF3, -OCF2CF2CF3, l=20,4-26,9, m=10,8-16,l, n=3,7-6,2 со среднечисленной молекулярной массой 4300-5700. Технический результат - получение низкомолекулярных тройных сополимеров этилена, обладающих высокой текучестью при температурах 0-50°С, на основе которых в отсутствие растворителя могут быть получены герметики холодного отверждения, обладающие высокой стабильностью в полярных растворителях и щелочных средах. 3 пр., 1 табл.
