摘要:
In a rubber-filler composite, the filler is uniformly finely dispersed, thereby improving low heat build-up, fatigue resistance and processability of a rubber composition. The rubber-filler composite is obtained by irradiating a filler slurry containing a filler such as carbon black or silica with high amplitude ultrasonic waves having amplitude of 80 μm or more to finely disperse the filler in the slurry, and mixing the dispersion-treated filler slurry with a rubber latex such as a natural rubber latex while conducting irradiation with high amplitude ultrasonic waves having amplitude of 80 μm or more, followed by coagulating and drying.

The present invention is drawn to surface-crosslinked latex particulates, corresponding latex suspensions, ink-jet inks, and methods for making the latex particulates. A latex suspension can include a fluid medium and surface-crosslinked latex particulates. The surface-crosslinked latex particulates can be devoid of substantially all crosslinking below the particulate surface. Such surface-crosslinked latex particulates can be prepared with a plurality of monomers and at least one crosslinking agent.

Reduced allergenicity natural rubber latex articles having otherwise normal physical, mechanical, and chemical properties are produced by directly sequestering the antigenic components on one surface of the article followed by inducing the remaining antigenic components of the natural rubber latex to bloom onto and adjacent to the opposed surface of the article prior to treatment with a subsequent screening reagent to sequester the remaining antigenic compounds.

The present invention discloses a molded article having a surface feature created by a light reactive agent interacting with light from a light source, and a method for making the same. The article is molded from a slurry comprised of an aqueous solution that includes a plurality of fibers and a light reactive agent. The slurry is molded into a three-dimensional solid fibrous molded part. The solid fibrous molded part is exposed to a light source such that the light reacts with the light reactive agent to create at least one surface feature. The surface feature can be, for example, a texture or a color change.

In various embodiments, methods for producing aqueous polyisoprene latex from natural cis-1,4-polyisoprene are described. The natural cis-1,4-polyisoprene may be sourced from guayule scrubs. In various embodiments, the method comprises extracting guayule plant material to form a miscella, fractionating the miscella to a preliminary cement, diluting the preliminary cement to a cement for dispersing, dispersing the cement in an aqueous surfactant mixture under high shear to produce an emulsion, and de-solventizing the emulsion to produce an aqueous latex dispersion. The rubber solids level can then be adjusted by centrifugation and dilution in water to produce a final aqueous cis-1,4-polyisoprene latex.

The present invention provides a method for producing rubber particles bound to a membrane-associated protein by cell-free protein synthesis. The present invention relates to a method for producing rubber particles bound to a membrane-associated protein, the method including the step of performing protein synthesis in the presence of both rubber particles and a cell-free protein synthesis solution containing an mRNA coding for a membrane-associated protein to bind the membrane-associated protein to the rubber particles.
