The present invention relates to a hydrogel useful to promote neurotization, osteogenesis and angiogenesis.

Disclosed is a method for preparing a bilayer scaffold through single process comprising: preparing a first polymer aqueous solution; adding a second polymer into the first polymer aqueous solution and stirring a reactant; adding a surfactant into the stirred reactant and stirring the reactant at high temperature and high speed; freeze-drying the stirred reactant thereby obtaining a sponge; dipping the sponge in a cross-linking agent thereby rendering be cross-linked; and freeze-drying the cross-linked reactant.

Copper clad laminates and a resin composition and a pre-preg and a laminate using the composition. The resin composition contains: (A) a prepolymer of vinyl thermosetting polyphenylene ether and a bifunctional maleimide or a multifunctional maleimide; and, (B) a polyolefin resin. Employing the prepolymer of vinyl thermosetting polyphenylene ether and the bifunctional maleimide or the multifunctional maleimide, solves the problem of incompatibility of the bifunctional maleimide or the multifunctional maleimide with the vinyl thermosetting polyphenylene ether and the polyolefin resin. An aqueous glue solution so mixed is uniform and consistent, the prepreg has a uniform expression, and a substrate resin area is free of a phase-separation problem.

The thermoplastic elastomer composition contains a thermoplastic elastomer and a pigment.

The present invention concerns a composition comprising at least one polymer, wherein the polymer is in the form of polymer particles, and wherein the composition contains at least one additive, wherein the additive is in a proportion of at most 2% by weight of the composition. Furthermore, the present invention concerns a method for the production of the composition in accordance with the invention, as well as a method for the production of an article comprising the composition in accordance with the invention. Finally, the present invention concerns the use of the composition in accordance with the invention.

Disclosed are latexes, suspensions, and colloids having a cationic antimicrobial compound complexed with an anionic surfactant. The surfactant may have greater affinity for the antimicrobial compound than other anionic surfactants and other anions in the latex, suspension, or colloid that contribute to disperse phase stability to prevent disrupting the dispersions. Dispersions containing the antimicrobial compound may therefore have a shelf life comparable to dispersions that are otherwise identical but lack the cationic antimicrobial compound and its complexed anionic surfactant. Coatings made with the complexes can exhibit essentially undiminished antimicrobial activity.
