LOW COMPRESSION SET THERMOPLASTIC GEL AND CABLE GEL SEAL ARRANGEMENT
Disclosed herein are various cable gel seal arrangements and thermoplastic gels useful therein. The thermoplastic gels are prepared from a composition including a styrene triblock copolymer, a styrene diblock copolymer, an oil extender, and an additive selected from poly(2,6-dimethyl-1,4-phenylene oxide), a C9 resin, poly(alpha-methylstyrene), a coumarone-indene resin, and combinations thereof, wherein the additive has a T.sub.g from about 95° C. to about 200° C. The thermoplastic gels advantageously exhibit low compression set.
Microfibrillated cellulose as a crosslinking agent
The present invention relates to a composition for use as an adhesive, paint, coating, resin, (surface) size, composite, gel or hydrogel, said composition comprising microfibrillated cellulose (“MFC”). In addition to microfibrillated cellulose, these compositions comprise at least one solvent, said solvent preferably comprising or consisting of water, and at least one compound that is (a) capable of polymerizing, or has already partly or fully, polymerized, and that (b) has at least two groups available for hydrogen bonding, preferably OH groups, that are capable of crosslinking with at least one functional group of the microfibrillated cellulose. In these compositions, the microfibrillated cellulose primarily functions as a crosslinking agent (while it is by no means excluded that the microfibrillated cellulose additionally has other functionalities, such as acting as viscosity modifier and/or thixotropic additive), integrating the compound that (a) is capable of polymerizing or that has already partly or fully, polymerized, and that (b) has at least two groups available for hydrogen bonding, into a gel-like three-dimensional network.
POLYSACCHARIDE-ELASTOMER MASTERBATCH COMPOSITIONS
Disclosed herein are polysaccharide-elastomer masterbatch compositions and processes for preparing the masterbatch compositions. One method comprises a step of a) mixing i) an aqueous polysaccharide dispersion, or ii) a basic aqueous polysaccharide solution, with a rubber latex solution containing a rubber component to form a mixture. The method further comprises the steps of: b) coagulating the mixture obtained in step a) to produce a coagulated mass; and c) drying the coagulated mass obtained in step b). The masterbatch compositions are useful in preparing rubber-containing articles.

EMULSION COMPOSITION OF AN ORGANOHYDROGEN POLYSILOXANE AND AN ADDITION-CURABLE SILICONE EMULSION COMPOSITION COMPRISING THE SAME
One of the purposes of the present invention is to provide an SiH group-containing polysiloxane emulsion composition having a less risk of expansion of a container due to the dehydrogenation reaction with time during storage, causing less deterioration in its performance, and having an excellent shelf life. Another purpose of the present invention is to provide an addition-curable silicone emulsion composition comprising the aforesaid emulsion composition and having excellent curability. Another purpose is to provide a cured film obtained by curing the aforesaid addition-curable silicone emulsion composition and having excellent light releasability from an adhesive. The present invention provides an emulsion composition comprising components (A), (B), (C) and (E): 100 parts by mass of (A) organohydrogenpolysiloxane having at least two hydrogen atoms each bonded to a silicon atom (i.e., SiH group) in one molecule, 0.1 to 20 parts by mass of (B) a nonionic surfactant, 0.01 to 50 parts by mass of (C) a buffer solution having a pH in a range of 4.0 to 6.0 at 25° C., and 30 to 10000 parts by mass of (E) water.
FIBROUS CELLULOSE COMPOSITE RESIN AND PRODUCTION METHOD THEREFOR
A fibrous cellulose composite resin excellent in strength, and a method for producing the same. The fibrous cellulose composite resin includes microfiber cellulose, a resin, and an acid-modified resin, wherein the microfiber cellulose has hydroxyl groups, which are substituted with carbamate groups, and has been washed and defibrated into an average fiber width of 0.1 μm or larger, in which the amount of the byproduct is 10% or less per 100 parts by mass of a carbamate-modified cellulose. The production method includes heat-treating a cellulose raw material and urea to obtain a carbamate-modified cellulose, washing the carbamate-modified cellulose, defibrating the carbamate-modified cellulose to obtain a dispersion of carbamate-modified microfiber cellulose having an average fiber width of 0.1 μm or larger, mixing the dispersion and an acid-modified resin to obtain a material containing carbamate-modified microfiber cellulose, and kneading the material with a resin to obtain a composite resin.
