摘要： A porous polyolefin film laminate favorably employable as a separator film for a nonaqueous lithium ion battery is composed of at least three polyolefin films, in which at least one polyolefin film preferably is a polyethylene film and at least two polyolefin films preferably are polypropylene films. The polyolefin films are combined to form a united film laminate having a pore volume of 30-80%, a maximum pore size of 0.02-2 .mu.m, a shutdown temperature lower than the melting point of the polyethylene film by 1-5.degree.C. The porous polyolefin film laminate can be prepared by heating the polypropylene film and the polyethylene film independently, combining the films under pressure and heating, stretching twice the combined films at a relatively low temperature and then at a relatively high temperature, and fixing the stretched film.

摘要： PURPOSE:To prepare a hydrophilic polyolefin porous film which is produced by hydrophilizing a porous film with a specific hydrophilizing treatment solution, thus is suitable for a cell separator, gas separation, bacterial filtration or the like because it is low in electric resistance (membrane resistance) and the dispersion of the electric and membrane resistances and excellent in quality and quality stability. CONSTITUTION:This film is obtained by hydrophilizing (A) a porous film made of PE or PP with (B) a treatment solution containing nonionic surfactant of polyoxyethylene alkylphenyl ether of the formula (R is C9H19, C8H17, (n) 4-9). Preferably, the component A has 30-60% void volume and 0.05-0.35mum maximum pore diameter, and this film has an electric resistance of 10-1,000mOMEGA.cm in 10N aqueous alkali. The film s prepared by soaking the component A in a hydrophilizing solution prepared by dissolving 0.5-10wt.% of a nonionic surfactant of the formula in a mixed solution of ethanol and water at a mixing weight ratio of 80/20-0/100 for more than 20 seconds and drying the product at 40-130 deg.C.

摘要： PURPOSE:To provide a thin separator for aprotic electrolytic battery which has small electric resistance and excellent mechanical strength and allows to set the block temperature to a desired value according to negative electrode active material. CONSTITUTION:A polyethylene porous film having thickness 8mum, porosity 49% and average pore diameter 0.123mum and a polypropylene porous film having thickness 18mum, porosity 52%, average pore diameter 0.190mum are formed according to a disclosed manufacturing method. The both are laminated and pressed to each other at 134 deg.C by means of roll press to form a laminated film. The laminated film is nearly equal to the porous film having the same thickness in rupture strength, load, elongation and elasticity, and its peeling strength between films is 0.4gf/cm. The block temperature is 140 deg.C lower than that of polypropylene porous film, and when the laminated film is held at 170 deg.C higher than the block temperature by 20 deg.C or more, it keeps the form of the porous film and is never fused.

摘要： PURPOSE:To prepare a molded product reduced in a flaw such as warpage or sinking and having no air bubbles present in the vicinity of the surface thereof, by injecting a liquid stock material having inert gas dissolved therein to perform polymerizing and foaming molding. CONSTITUTION:As a method for dissolving inert gas in a liquid stock material, a method for supplying pressurized inert gas to the upper gaseous phase part of a stock material tank having a liquid stock material received therein is employed. The pressure of inert gas in the stock material tank is pref. set to 0.2-1.5kg/cm (gauge pressure), especially, to 0.3-1.2kg/cm (gauge pressure). By performing the reactive injection molding of the liquid stock material having inert gas dissolved therein by the above-mentioned method, a molded product of which the foaming magnification is 1.02-1.15 times, pref. 1.03-1.12 times can be obtained. If the pressure of the inert gas in the stock material tank is excessively low, no effect for compensating molding shrinkage is developed and, if said pressure is excessively high, a large number of air bubbles or pinholes are generated to the surface of the molded product and not only surface appearance is damaged but also adverse effect is imparted to paining property or the strength of the molded product is lowered.
