CELLULOSE FIBER-CONTAINING MATERIAL, FLUFFED CELLULOSE, AND COMPOSITION
It is an object of the present invention to provide a fluffed cellulose having totally new properties that have not conventionally existed, and a cellulose fiber-containing material capable of realizing the same. The present invention relates to a cellulose fiber-containing material comprising cellulose fibers having anionic groups, wherein the yield of the cellulose fiber-containing material measured by the following measurement method is 50% by mass or more, the cellulose fiber-containing material has organic onium ions as counterions of the anionic groups, and the organic onium ions satisfy a predetermined condition.
Highly Heat-Resistant Resin Composite Including Chemically Modified, Fine Cellulose Fibers
Provided is a resin composite having high mechanical properties which make the resin composite moldable into and usable as members for use in applications such as vehicle-mounted members and electrical materials. The resin composite comprises 0.5-40 mass % chemically modified, fine cellulose fibers and a resin, wherein the chemically modified, fine cellulose fibers have a pyrolysis initiation temperature (T.sub.D) of 270° C. or higher, a number-average fiber diameter of 10 nm or larger but less than 1 μm, and a degree of crystallinity of 60% or higher. In a preferred embodiment, the chemically modified, fine cellulose fibers have a coefficient of variation (CV) in DS unevenness ratio, DSs/DSt, of 50% or less, the DS unevenness ratio being the ratio of the modification degree (DSs) of the surface layers of the fibers to the modification degree (DSt) of the whole of the fibers.
POLISHING METHOD, POLISHING AGENT AND CLEANING AGENT FOR POLISHING
According to one embodiment, a polishing method includes supplying a polishing agent to be between a polishing pad and to-be-polished surface, then polishing the to-be-polished surface with the polishing agent while rotating at least one of the to-be-polished surface and the polishing pad. The polishing agent includes abrasive grains and an organic polymer. The organic polymer makes a reversible phase transition between a gel state and a sol state depending on temperature.
Multipurpose shrink sleeve printing ink
Described herein is a printing ink or coating composition that includes: (a) one or more elastomeric polyurethane resins with amine functionality having a glass transition temperature of about −45° C. to about −70° C.; (b) one or more acrylic resins based on a methacrylate/styrene co-polymer with a glass transition temperature of about 45° C. to about 110° C.; (c) one or more nitrocellulose binders; (d) one or more solvents; and (e) optionally, one or more waxes and/or one or more colorants. The inks and coating compositions are well suited for printing onto shrink sleeve label substrates, such as by flexographic and gravure printing. The inks and coatings provide exceptional printability and resistance to chemicals, to softening, to re-wetting, and to set-off.

Grafted polymers
A process is provided for grafting CRP synthesized polymers to dienes and polyolefins in the presence of a CRP controlling agent. Chain scission is minimal. Graft yield can be high and is proportional to the amount of CRP controlling agent added. The grafting process can be carried out either in a molten phase, preferably by reactive extrusion, or in a solvent-based process. The process provides novel families of grafted polyolefins and dienes, which show promising applications as new materials and as additives in the polymer industry.
