摘要： A polyethylene composition and the use thereof, and a polyolefin microporous breathable film prepared therefrom. The polyethylene composition comprises a polyethylene matrix resin and a pore-forming agent, wherein the content of the pore-forming agent is 30-110 parts by weight on the basis of 100 parts by weight of the polyethylene matrix resin, the pore-foaming agent comprises maleic anhydride copolymer microspheres, a copolymer in the microsphere comprises a structural unit A from maleic anhydride, a structural unit B from a vinyl-containing comonomer M and an optional cross-linking structure unit from a cross-linking agent, and the average particle size of the maleic anhydride copolymer microspheres is 500-2000 nm. The polyethylene composition can be used for preparing a breathable film without using a coupling agent, a dispersing agent and/or a surfactant, and achieves uniform air permeability and a high water vapor transmission rate. The film can be used for breathable composite products such as sanitary products, medical products, and food packaging or building products.

摘要： The invention relates to a field of polymer preparation and discloses a method for promoting phase-separation of polymer solution. The phase-separation method of polymer solution of the invention comprises: at least a portion of the polymer solution is subjected to a heat treatment under flowing so that the polymer solution is divided into a clear liquid phase and a concentrated liquid phase, wherein the Reynolds number of the polymer solution flowing is 0.2-30. By performing the heat treatment under specific Reynolds number conditions, the invention permits to reduce the temperature of phase-separation of solution, reduce the time of phase-separation of solution, and significantly reduce the material consumption and energy consumption of the entire process, compared with the existing technology that only performs phase-separation through heat treatment.
