Abstract: A foamable composition for polyurethane foam is provided which advantageously improves heat insulating properties, a long-term stability, and a dimensional stability of a polyurethane foam that is produced by using carbon dioxide as a blowing agent. Further, a polyurethane foam which has excellent heat insulating properties is provided by foaming and curing the foamable composition for polyurethane. In the production of the polyurethane foam in which carbon dioxide is used in the foaming, a polyol component is used which includes a phenolic resin polyol that is obtained by adding at least one alkylene oxide to a phenolic novolak resin, and an aromatic amine polyol that is obtained by adding at least one alkylene oxide to an aromatic diamine such that the total amount thereof is 60% or more by mass, based on the total polyol component.

Abstract: An orally administered adsorbent which has a high ability of adsorbing indoxylsulfuric acid, indoleacetic acid, and indole, a method permitting easy and advantageous production of the same, and a drug using the same. The orally administered adsorbent is obtained from spherical particles of activated carbon by carbonizing and activating spherical particles of a furfuryl alcohol resin obtained by resinifying furfuryl alcohol through a self-condensation reaction and curing the resinified furfuryl alcohol.
