Abstract: The present invention relates to a method for preparing a polyurethane synthetic leather having uniform fine pores therein, by coagulating a polyurethane mixture solution prepared by mixing an additive containing sucrose with a polyurethane resin composition, and then removing the additive in the coagulated polyurethane mixture solution. The present invention can not only form a smooth surface after a sanding process but also improve an air permeability and softness due to fine pores formed in the polyurethane synthetic leather. In addition, the size and density of the fine pores can be optionally adjusted by adjusting the content of the additive, and the present invention can provide various types of synthetic leathers depending on the product use.

Abstract: Microporous material comprising a polypropylene polymer having at least 20 percent crystallinity; and a compatible, amorphous, glassy polymer, wherein said polymers are miscible in a compound when heated above the melting temperature of the polypropylene polymer and wherein a polypropylene polymer phase separates from the compound when cooled below the crystallization temperature of the polypropylene polymer. Microporous material is made by a thermally induced phase separation process using a compound such as mineral oil to form one phase containing both polymers. The pores of the microporous material resist collapse during processing. Membranes made of this material are useful as battery separators having a good combination of strength, porosity, and ionic resistance when imbibed with an electrolyte.

Abstract: A resin product wherein a resin B has pillar structures or lamellar structures inside a resin A is molded by kneading the resin A and the resin B that serves as a base material in an injection molding machine while heating both of the resins to at least a temperature at which both of the resins are melted at least partially. The resin product is soaked in a solution having higher erosion capability with respect to the resin A than the resin B, thereby dissolving the resin B and forming an uneven structure on the surface. As a result, an uneven structure having various shapes, densities or depths which are precisely adjustable can be formed at low cost. And provided are a resin structure and a production method thereof that can maintain wettability control or optical property control of the molded article over a long period of time.
