摘要： A process for the preparation of composite particle dispersons is disclosed. The composite particles have a core particle 1 surrounded by a second material 2. Normally a core shell particle will be formed and the second material which forms the shell will be a polymer material.The composite particles are formed by mixing a dispersion of polymer particles with pre-formed core material particles. The polymer particles are stabilized relative to one another, and the core material particles are destabilized in the dispersion so that they are able to make contact with the surfaces of the polymer particles. The process takes place at a temperature above the operative glass transition temperature of the polymer, and in the process the polymer spreads over the surface of the core particle so that the core particle is encapsulated.The process will proceed, and composite particles will be formed, when the interfacial energies of the three interfaces (core/polymer: core/liquid: polymer/liquid) and the relative volumes of the core particles and polymer particles are related to one another in accordance with an equation which is set out in the specification.

摘要： A pigment composition is composed of an intimate mixture of an organic pigment and a polymer. The content of the organic pigment is 75-95 wt. % based on the whole pigment composition. Monomers which form the polymer include 0-40 wt. % of styrene, 20-70 wt. % of a methacrylic ester and 20-50 wt. % of methacrylic acid. The total proportion of styrene, the methacrylic ester and methacrylic acid is at least 85 wt. % of the entire monomers. The pigment composition is prepared by mixing the organic pigment with an aqueous alkaline solution, which contains the polymer and an alkali metal salt, alkali metal hydroxide, lower amine or ammonium, to form an aqueous dispersion. The organic pigment and polymer are then subjected to coprecipitation, preferably, by lowering the pH of the aqueous dispersion beyond 7.0.

摘要： A homogeneous predispersed fiber composition useful for dispersing a fibrous material in a rubber or plastic compound stock, said composition comprising a fibrous material and a rubber or plastic polymer binder, wherein said composition is prepared by mixing a latex of the rubber or plastic polymer with the fibrous material to form a wetted fiber mixture, mixing a coagulant with the wetted fiber mixture thereby forming the predispersed fiber composition, wherein the total amount of water present in the wetted fiber mixture prior to coagulation is substantially equal to that required to completely wet the fibrous material by either capillary action, surface adsorption or a combination thereof.

摘要： Homogeneous blends of elastomers are produced by mixing an elastomer in latex form with an elastomer dissolved in an organic solvent to form a pseudoemulsion in which the two elastomers are thoroughly mixed in the liquid phase. Both of the mixed elastomers are then coagulated and agglutinated to provide the blend. The latex is at least partially coagulated prior to coagulation of the dissolved elastomer. Subsequently the solvent is vaporized and removed from the pseudoemulsion to effect coagulation of the dissolved elastomer in the presence of elastomer from the latex which has already been coagulated, and the two elastomers are thus agglutinated.

THE NEEDLE-LIKE ASSEMBLIES ARE FORMED BY AGITATING AT AN ELEVATED TEMPERATURE A MINOR QUANTITY OF DISCONTINUOUS FIBERS WITH AN EMULSION COMPRISING A MINOR QUANTITY OF AN A-STAGE EPOXY RESIN AND A CURING AGENT FOR SAID EPOXY RESIN WITHIN A MAJOR QUANTITY OF A CONTINUOUS PHASE COMPRISING A MIXTURE OF GLYCEROL, WATER, AND A WATER-SOUBLE NONIONIC SURFACE-ACTIVE AGENT. THE PRODUCT OF THE PRESENT INVENTION IS RECOVERED FROM THE SYSTEM IN WHICH IS FORMED AND IS SUITABLE FOR USE AS A GRANULAR MOLDABLE MATERIAL WHICH CONSISTS OF ESSENTIALLY UNIDIRECTIONALLY ALIGNED FIBERS IMPREGNATED WITH A B-STAGE EPOXY RESIN.
