    摘要： Novel nonionic cellulose ethers exhibit a reduced degree of thermal thinning and are efficient thickeners at elevated temperatures. The nonionic cellulose ether has hydroxyethyl groups and is further substituted with one or more hydrophobic substituents. The cellulose ether further has at least one of the properties a), b) or c): a) a retained dynamic viscosity, % η80/25, of at least 30 percent, wherein % η80/25=[dynamic solution viscosity at 80° C./dynamic solution viscosity at 25° C.] 100, the dynamic solution viscosity at 25° C. and 80° C. being measured as 1% aqueous solution; b) a storage modulus of at least 15 Pascals at 25° C. and a retained storage modulus, % G′80/25, of at least 12 percent, wherein % G′80/25=[storage modulus at 80° C./storage modulus at 25° C.] 100, the storage modulus at 25° C. and 80° C. being measured as a 1% aqueous solution; c) a critical association concentration of less than 15 ppm as measured by light-scattering.

    摘要： Provided is an entry sheet for drilling that, compared with a conventional entry sheet for drilling, has better hole position accuracy, can suppress drill bit breakage, and exhibits less processing chips wrapping around the drill bit. This entry sheet for drilling includes a metallic support foil and a layer comprising a resin composition that is formed on at least one surface of the metallic support foil, wherein the resin composition contains a cellulose derivative (A) and a water-soluble resin (B), the cellulose derivative (A) includes a hydroxyalkyl cellulose and/or a carboxyalkyl cellulose having a weight average molecular weight of 20,000 to 350,000, and based on 100 parts by mass of the resin composition, the content of the cellulose derivative (A) is 5 to 40 parts by mass and the content of the water-soluble resin (B) is 60 to 95 parts by mass.
