摘要： Described are microporous materials including (a) a polymeric matrix component; (b) a finely divided, particulate inorganic filler component dispersed throughout the polymeric matrix; and (c) a network of interconnecting pores communicating substantially throughout the microporous material, the pores constituting 10 to 80 percent by volume of the microporous material. The polymeric component is based on (i) 5 to 100 weight percent based on total weight of component (a) of low melt flow index polypropylene; (ii) 0 to 90 weight percent based on total weight of component (a) of ultrahigh molecular weight polyethylene; and (iii) 0 to 90 weight percent based on total weight of component (a) of high density polyethylene. Also provided are multi-layer articles prepared from the microporous materials.

摘要： Particles comprising particulate amorphous precipitated silica in association with from 5 to 10 percent by weight sodium sulfate and less than 10 percent by weight water, wherein the percentages are based on the weight of the silica, the sodium sulfate, and the water, which particles have a BET surface area of from 100 to 300 m.sup.2 /g, a total intruded volume from 1.8 to 3.6 cm.sup.3 /g, and a DBP oil absorption of from 180 to 320 cm.sup.3 /100 g, may be employed in microporous battery separators to introduce all or a portion of the desired sodium sulfate to the battery electrolyte. Moreover the enhanced amount of sodium sulfate enhances silica characteristics and battery separator production.
