The short-chain diol compound has a number-average molecular weight of 30 to 400. The diisocyanate compound has a number-average molecular weight of 100 to 1,000 at an NCO/OH equivalency in the range of 1-5. Microorganisms multiply rapidly at the surface and interior of the carrier. Preferred adherence and proliferation of desired microorganisms is possible by appropriately selecting substances incorporated as microorganism nutrients.

The swollen gel may be in the form of beads of 1.0 to 20 mm, and the resin when swollen with water has a water absorption coefficient of 500 to 3500%. Resin beads may be swollen in a suspension of a biocatalyst such as animal cells, plant cells, microorganisms or protozoans to bind and immobilize the biocatalyst to form a bioreactor. The microorganisms can be nitrate bacteria, denitrification bacteria or Hyphomycetes, and the bioreactor may be used to treat waste water or for deodorizing. The crosslinked N-vinylcarboxamide resin contains a repeating unit shown by formula (A) below crosslinked with a crosslinking agent. ##STR1## wherein R.sup.1 and R.sup.2 represent independently a hydrogen atom or a methyl group.

摘要： An active material powder mixture for batteries or a carbonaceous material powder mixture for electrical double-layer capacitors is composed of a battery active material or a carbonaceous material in combination with an electrically conductive powder that adheres to the periphery of the active material or carbonaceous material and has an average particle size of 10 nm to 10 μm. The battery active material powder mixture may be used to make electrodes for secondary batteries. The carbonaceous material powder mixture may be used to make polarizable electrodes for electrical double-layer capacitors. Secondary cells produced using the active material powder mixture can lower an impedance of an electrode and operate at a high capacity and a high current, have a high rate property, and are thus well-suited for use as lithium secondary cells and lithium ion secondary cells. Electrical double-layer capacitors made using the carbonaceous material powder mixture have a high output voltage and a high capacity because of a low impedance.
