Abstract: A normally hydrophilic microporous material having a polymeric matrix and a filler dispersed throughout the matrix wherein the filler contains active polar groups, is rendered hydrophobic by exposing the material to a reactive compound. In one preferred embodiment of the invention the reactive compound is a silane or a silazane whereas in another preferred embodiment the reactive compound is a Werner-type complex of fatty acids coordinated with a metal. The treated microporous material is rendered impervious to water-based liquids but remains pervious with respect to vapors or gases.

Abstract: This invention relates to coated paper-like plastic films having a microporous surface layer and a method of producing the same. Such a coated plastic film is produced by coating plastic polymeric films with a coating composition comprising a resin, a plasticizer, an inorganic fine powder and dimethylformamide and then the coated plastic film is treated with water and subjected to drying. Also, in accordance with this invention, the coated plastic film is subjected to a heat-treatment before or after the coated plastic film is treated with water or after the coated plastic polymeric film is dried.

Abstract: A POROUS POLYMERIC SHEET HAVING A SPECFIC GRAVITY OF LESS THAN 0.7 AND A THICKNESS OF 0.05 TO 2.0 MM. AND CONTAINING PORES INCLINED AT AN ANGLE OF LESS THAN 80* AGAINST THE PLANE OF THE SHEET AND HAVING A LENGTH OF 0.03 TO 10 MM. A SHEET MATERIAL COMPRISING SAID POROUS POLYMERIC SHEET AND A SUBSTRATE BOUND TO THE LOWER SURFACE OF SAID POROUS POLYMERIC SHEET. SAID POROUS POLYMERIC SHEET IS PRODUCED BY IMMERSING A POLYMER SOLUTION APPLIED TO A SUPPORT INTO A COAGULATION BATH UNDER A CONDITION OF RAPID COAGULATION RAPIDLY THE UPPER PORTION OF THE SOLUTION AND TO FORM MACROPORES IN THE INNER PORTION; STRESSING THE UPPER PORTION IN TRANSVERSE DIRECTION, THAT IS, A DIRECTION PARALLEL TO THE PLANE OF THE SUPPORT, IN THE BATH TO SHIFT THE UPPER PORTION TO TRANSVERSE DIRECTION AND TO INCLINE THE PORES FORMED; TREATING FURTHER THE LAYER WITH THE BATH TO COMPLETE THE COAGULATION, THEREBY FORMING POROUS STRUCTURE CONTAINING PORES INCLINED AT AN ANGLE OF LESS THAN 80* AGAINST THE PLANE; AND PEELING OFF THE RESULTING POROUS POLYMERIC SHEET FROM THE SUPPORT.
