Abstract: Carbon black compositions comprising ethoxylated esters or polyethers and carbon black. The compositions may be produced by incorporating ethoxylated esters or polyethers onto fluffy carbon black in a pelletizing process to produce free flowing, low dust, attrition resistant carbon black pellets which are easily dispersible in most polymeric systems and impart to polymer compositions enhanced rheological and mechanical properties. The polymeric compositions have particular utility as semiconductive compositions or masterbatch compositions.

Abstract: This disclosure relates to a process for preparing co-pelletized submicron pigment powder/polymer pellets in a dry drum pelletizing process using a thermoplastic polymer as seed pellets. Also disclosed is a process for using the co-pelletized product either for formation of masterbatch or for directly introducing at least one pigment into thermoplastic media.

Abstract: A particulate inorganic solid, especially hydrated alumina or magnesium hydroxide, which has been treated with a hydroxybenzene derivative of a defined type, particularly a gallate. The treated solid may be incorporated into a polymer especially a thermoplastic polymer such as polypropylene. Alternatively, the solid, the hydroxybenzene derivative and the polymer can be blended together. The composition obtained can be processed even when containing 70% by weight of the inorganic solid.

Abstract: Curable epoxide resin compositions having improved mechanical and fire-resistant properties comprise an epoxide resin adducted with an elastomer polymer including a chlorinated monomer such as a chlorinated butadiene, vinyl chloride or vinylidene chloride and an unsaturated carboxylic acid monomer such as acrylic acid or methacrylic acid. The composition may be produced by stirring an aqueous latex of the polymer into the liquid resin, with heating if necessary. The compositions can be cured with conventional curing agents and can replace ordinary epoxide resins in most applications without any change in procedure.
