Abstract: The present invention provides a process for producing a fiber reinforced composite which contains the reinforcing fibers uniformly dispersed therein and therefore has uniformity of strength. The process comprises;preparing an aqueous slurry which comprises reinforcing fibers, water-soluble organic polymers A charged in water and particulate organic polymers,adding thereto water-soluble organic polymers B charged opposite to said organic polymers A in water to flocculate the solid components in said aqueous slurry, andthen removing aqueous medium and molding.

Abstract: A resole resin in the form of microspherical particles whose surfaces are partly or entirely covered with a coating of a substantially water-insoluble inorganic salt and which are not larger than 500 .mu.m in size, and a process for producing such resole resin. The resole resin comprises solid particles that are highly heat reactive and can be stored in a stable manner for a prolonged period. The resin particles can be used with good results in all fields of applications (e.g., moldings, laminations and binders) where conventional phenolic resins are used.

Abstract: A process for producing microspherical cured phenolic resin particles having a particle diameter of not more than about 100 .mu.m, which comprises reacting a novolak resin, a phenol and an aldehyde in an aqueous medium in the presence of a basic catalyst and an emulsion stabilizer. Novel microspherical cured phenolic resin particles are produced by this process. The resin particles have excellent impact strength and mechanical properties, a sharp particle size distribution, and a low secondary agglomerate content, and because of these properties, are useful as an excellent modifier or filler for various plastics and rubbers.
