Provided is a conductive foam roll having a high surface opening ratio that achieves both cleaning performance and low resistance. A conductive foam roll 10 includes a shaft body 12 and a conductive foam layer 14 around the shaft body 12, wherein the conductive foam layer 14 has a surface opening ratio of 50% to 90%, and wherein the conductive foam layer 14 contains an ionic conductive agent that contains salt of diallyl-type ammonium cations, and at least one selected from the group consisting of N,N-bis(trifluoromethanesulfonyl)imide anions, and N,N-bis(fluorosulfonyl)imide anions.

The present invention relates to adhesives which are characterized in that they cure in the absence of water and at room temperature with the formation of isocyanurate groups.

There is described a foamed isocyanate-based polymer derived from a reaction mixture comprising: an isocyanate; a polyol composition comprising a first prescribed amount of polymer particles dispersed in a base polyol; a second prescribed amount of biomass-based carbonaceous particulate material; and a blowing agent. In one embodiement, the foamed isocyanate-based polymer having an Indentation Force Deflection when measured pursuant to ASTM D3574-11 which is within about 15% as that of a reference foam produced by omitting the biomass-based carbonaceous particulate material from the reaction mixture and increasing the amount of polymer particles in the polymer polyol composition to equal the sum of the first prescribed amount and the second prescribed amount. In another embodiment, the foamed polymer has a cellular matrix comprising a plurality of interconnected struts, the biomass-based carbonaceous particulate material conferring to the cellular matrix a load efficiency of at least about 5 Newtons/weight % of biomass-based carbonaceous particulate material. A process to produce the foamed isocyanate-based polymer is also described. A polyol-based dispersion to produce the foamed isocyanate-based polymer is also described. It has been discovered that a relatively expensive petroleum-based copolymer polyol can be fully substituted by a relative inexpensive bio-based (amorphous carbon) dispersion with no significant compromise in important physical properties in the resulting polyurethane foam.

Polymer polyols (PMPOs), processes for their production, and the use of such PMPOs, particularly in the production of flexible polyurethane foams. The PMPOs are produced using an ethylenically unsaturated composition that includes tertiary amino group-containing ethylenically unsaturated compound.
