Предполагаемое изобретение относится к пористым пленкам на основе полиолефинов, получаемых из растворов и может быть использовано в химической технологии при получении сепараторов аккумуляторных батарей. Предложена композиция, содержащая сэвилен, ксилол, бутилцеллозольв. Использование предлагаемой композиции позволяет получить мембраны с максимальным диаметром пор, не превышающем 2,5• 10-6м и прочностью при разрыве не менее 2,0 МПа, при этом общая пористость у мембран не менее 60%.The alleged invention relates to porous films based on polyolefins obtained from solutions and can be used in chemical technology for the production of battery separators. A composition comprising sevilen, xylene, butyl cellosolve is proposed. Using the proposed composition allows to obtain membranes with a maximum pore diameter of not more than 2.5 • 10 -6 m and a tensile strength of at least 2.0 MPa, while the total porosity of the membranes is not less than 60%.
