This invention provides a process for producing an epoxy resin composition having core / shell rubber particles (rubber-like polymer particles) dispersed in an epoxy resin, wherein an epoxy resin composition excellent in the dispersed state of rubber-like polymer particles in an epoxy resin with a reduced amount of contaminants is produced easily and efficiently. The epoxy resin composition having rubber-like polymer particles dispersed well in an epoxy resin with less contaminant is obtained by bringing an aqueous latex of rubber-like polymer particles (B) into contact with an organic medium (C) showing partial solubility in water, then bringing an organic medium (D) having lower partial solubility in water than that of the organic medium (C) into contact therewith to separate water substantially, to remove the rubber-like polymer particles as a dispersion (F) having the polymer particles dispersed in the organic medium, and mixing it with an epoxy resin (A), followed by distilling volatile components away.

A method and apparatus for selecting paths to route incoming traffic through a data communication network, which is capable of effectively dispersing the traffic load to the selected paths on the network and effectively optimizing the use of network resources. In a communication network, a plurality of label switched paths between an ingress node and an egress node are provided. Incoming traffic at the ingress node is labeled and delivered through the network to the egress node. In a method and apparatus for selecting paths to route the incoming traffic through the network, a plurality of forwarding equivalent class elements (FEC) of the incoming traffic at the ingress node are allocated for the plurality of label switched paths. The labeled traffic is delivered on the plurality of label switched paths on an FEC-element basis so as to route the labeled traffic through the network to the egress node. The traffic load on the respective label switched paths can be effectively dispersed and the sequence of data packets, sent by the same terminal, may be maintained.

Compositions and methods in which dry-committed fibers are substantially homogeneously dispersed throughout a fibrous composition. The fibrous composition is characterized as having sufficient yield stress and viscosity such that the shearing forces from the mixing apparatus are effectively transferred down to the fiber level. This is accomplished by means of an appropriate thickening agent, e.g, gelatinized starch. The dry-committed fibers are exemplified by flash dry fibers or fibrous sheets that have been cut or torn into fragments less than 2 cm across. Providing fibers that have been dry-committed greatly reduces the time that it takes to obtain substantially homogeneous dispersion of the fibers throughout the fibrous composition. This, in turn, reduces the risk of mixture spoilage and mechanical or chemical damage to the solid components within the fibrous composition.
