Abstract: A porous composition comprising a porous organic polymer (POP) fiber having a diameter of at least 100 nm and a length of at least 1 mm and pores having a size within a range of 10 nm to 5 microns distributed over the surface and volume of the POP fiber, wherein the organic polymer is insoluble in water and may be selected from, e.g., polyolefins, polyesters, polyamides, and polyacrylonitrile. Also described herein is a method for producing a POP fiber comprising: (i) forming a precursor fiber from a blend of an organic polymer and lignin, wherein the lignin is present in the form of domains within the precursor fiber; and (ii) washing the precursor fiber with a solvent that dissolves the lignin to result in the POP fiber. Also described herein is a method for removing oil from an oil-water mixture comprising contacting the oil-water mixture with the POP fibers.

Abstract: The present invention relates to a road paving method enabling one to provide an asphalt paving material layer in which both excellent stability and stress relaxation can be made compatible with each other, the method including
Step 1: a step of mixing asphalt, a thermoplastic elastomer, a polyester, and an aggregate to obtain an asphalt mixture, and
Step 2: a step of laying the asphalt mixture obtained in Step 1 on a road, thereby forming an asphalt paving material layer, wherein
the polyester has a softening point of 90° C. or higher and 140° C. or lower and a glass transition point of 40° C. or higher and 80° C. or lower, and
a ratio of the polyester is more than 17 parts by mass and 50 parts by mass or less based on 100 parts by mass of the asphalt.
