A xanthogen compound dispersion is formed by dispersing a xanthogen compound in water or alcohol, wherein a volume average particle size of the xanthogen compound is 0.001 to 9 ?m.

Various embodiments disclosed related to flexible fibrous surface-treating articles with low formaldehyde off-gassing. In various embodiments, the present invention provides a flexible fibrous surface-treating article including an open, lofty, nonwoven web including fibers. The flexible fibrous surface-treating article also includes a binder that coats the fibers of the nonwoven web. The binder includes a cured product of a curable composition including a latex and a crosslinker. The flexible fibrous surface-treating article heated to 65 C. in a closed space for 30 minutes emits less than about 6 micrograms of gaseous formaldehyde total per gram of the flexible fibrous surface-treating article.

A method for preparing a coupled polymer, the method comprising the steps of polymerizing monomer to form a reactive polymer and reacting the reactive polymer with a carboxylic or thiocarboxylic ester containing a nitro group, where the carboxylic or thiocarboxylic ester containing a nitro group includes a single nitro group.

The present invention relates to a binder composition for a secondary battery, including: a copolymer having a functional group; and an alkali metal ion bound to the functional group of the copolymer or with which a constituent element of the functional group is substituted. The binder composition exhibits enhanced adhesive strength and also exhibits low resistance due to the alkali metal ion included in the copolymer, and thus may exhibit more stable electrochemical performance.

A cross-linked rubber prepared by cross-linking a nitrile rubber composition including: a carboxyl group-containing highly saturated nitrile rubber containing 5 to 60 wt % of an ,-ethylenically unsaturated nitrile monomer unit, and an ,-ethylenically unsaturated monocarboxylic acid ester monomer unit, and having an iodine value of 120 or less; a surface treated silicate; and a polyamine-based cross-linking agent wherein a content is 0.1 to 20 parts by weight with respect to 100 parts by weight of the carboxyl group-containing highly saturated nitrile rubber, wherein when the rubber is subjected to a compression stress relaxation test wherein it is maintained at 150 C. while being compressed by 25%, the time until which the compression stress comes to be 50% of the initial compression stress at the start of the test, the compression stress after 30 minutes from the start of the test, is 300 hours or more.
