  • Patent number: 10836888
    Abstract: A power transmission belt is at least partially formed of a rubber composition. The rubber composition contains a rubber component, cellulose nanofibers, and carbon black. The amount of the cellulose nanofibers to be added is from 0.1 parts by mass to 20 parts by mass, relative to 100 parts by mass of the rubber component. The amount of the carbon black to be added is from 5 parts by mass to 80 parts by mass, relative to 100 parts by mass of the rubber component. The sum of the amount of the carbon black to be added and three times the amount of the cellulose nanofibers to be added is from 15 to 90.

  • Patent number: 10794450
    Abstract: A power transmission belt at least includes a bottom rubber layer. A rubber composition for forming the bottom rubber layer contains a rubber component, cellulose fine fibers, and short fibers. The cellulose fine fibers have an average diameter from 1 nm to 200 nm, and the rubber composition contains 0.5 parts by mass or more of the cellulose fine fibers relative to 100 parts by mass of the rubber component. The short fibers have an average diameter from 5 ?m to 30 ?m, and the rubber composition contains 1 part by mass or more of the short fibers relative to 100 parts by mass the rubber component.

  • Patent number: 10745588
    Abstract: This invention provides a silicon wafer polishing composition used in the presence of an abrasive. The composition comprises a silicon wafer polishing accelerator, an amide group-containing polymer, and water. The amide group-containing polymer has a building unit A in its main chain. The building unit A comprises a main chain carbon atom constituting the main chain of the amide group-containing polymer and a secondary amide group or a tertiary amide group. The carbonyl carbon atom constituting the secondary amide group or tertiary amide group is directly coupled to the main chain carbon atom.

  • Patent number: 10746257
    Abstract: Disclosed is a power transmission belt having a belt body made of rubber, and a cord embedded in the belt body so as to form a helical pattern having a pitch in a belt width direction. The cord is coated with an adhesion layer formed by an adhesion treatment and containing a rubber component, and the adhesion layer is in contact with a rubber composition containing cellulose-based fine fibers.

  • Patent number: 10717899
    Abstract: Provided are polishing compositions comprising a water-soluble polymer and water. The water-soluble polymer of an embodiment has a repeat unit that does not have any hydroxyl groups, and the water-soluble polymer has a hydroxyl group content in a range of 4 mmol/g or higher and 21 mmol/g or lower. The water-soluble polymer of another embodiment has a repeat unit A that has a hydroxyl group and a repeat unit B, and the number of moles of the repeat unit B in the total number of moles of all the repeat units of the water-soluble polymer is 5% or greater.
