Abstract: A method for preparing a conductive thermoplastic resin composition or an electric conductor includes the step of kneading (a) conductive resin master batch pellets of conductive carbon black and a thermoplastic resin in which the conductive carbon black accounts for 5 to 50% by weight relative to the total amount 100 parts by weight of the conductive carbon black and the thermoplastic resin, (b) a thermoplastic resin in a weight ratio: (a+b)/(a) ranging from 1.01 to 1.5. This method permits the production of a conductive carbon black-containing conductive resin composition and an electric conductor which show stable conductivity even within a high resistance region (having a surface resistivity ranging from 10.sup.6 to 10.sup.16 .OMEGA.), wherein the control of the conductivity is difficult.

Abstract: Apparatus and method for the production of hopper feedable thermoplastic pellets having zones or compartments which contain physically separated reactants which react only after being melt-mixed, as in a screw type extruder, reciproscrew injection machine, or similar device which heat forms pellets into a larger mass. This new class of thermoplastic molding materials relies mainly on the relatively slow reaction kinetics of contained large molecule molding materials to provide a time interval after melt-mixing of zoned pelletized reactants in an extruder barrel or injection molding machine. During this time period, the thermoplastic molding material is easily filled into injection molds. As the reaction progresses, the material becomes more viscous and such flow is difficult or impossible. The involved reactions may continue after demolding at room temperature during a post molding cure, or appliance service generated heat may cause post molding cure. Where a delayed reaction involves crosslinking and/or additional polymer molecular growth after molding, such crosslinking can bond adjacent molecules and reduce or prevent stress memory warpage of molded parts. Fibrous reinforcements may be included to aid in reducing post molding warpage. Foaming agents contained can, when molded by the Bradt Process, virtually eliminate weld lines in molded parts.

Abstract: A two step method of preparing fire retardant thermoplastic polymer granules from fire retarding agents and thermoplastic polymers in a stationary granulating cylinder containing mixing elements mounted to a central rotating shaft which fluidizes and throws contained materials toward the center of the cylinder, forcing axial and radial flows simultaneously on the materials thereby forming granules. In the first step, a fire retarding agent is mixed with a fluid thermoplastic polymer at a temperature exceeding the solidification point of the polymer until a homogeneous mixture is formed. In the second stage, the mixture is solidified by cooling while the granulating cylinder continues to operate until the fire retardant agent is bound together in homogeneous granular form by a matrix of solid thermoplastic polymer. Suitable fire retarding agents include alumina, phosphates, borates, melamine, melamine cyanurate, metal cyanurates, and halogenated phenols. The fluid thermoplastic polymer may be a metal or aqueous dispersions. Suitable polymers include polyolefins, polyphenyls, polyamides, polyfluocarbons, polycarbonates, polyurethanes, polyesters, and polyvinylidene chloride. The method allows preparation of thermoplastic granules, suitable for melt blending with other polymers, containing as much as 90 percent fire retardant agent. The fire retardant thermoplastic concentrate granule compositions prepared by this method are new and exhibit better physical properties at high active ingredient concentrations than compositions available heretofore. These new concentrated fire retardent compositions have improved properties of melt blending with other thermoplastics to impart fire retardency thereto.
