    摘要： Elastomer masterbatch is processed in a continuous compounder having multiple parallel elongate rotors axially oriented in an elongate processing chamber. Optionally, additional materials are compounded into the masterbatch, e.g., additives, other elastomeric compositions, etc. Preferably, the masterbatch then is further processed in an open mill. Excellent control of Mooney Viscosity is achieved. In certain preferred embodiments, elastomer composites are produced by novel continuous flow methods and apparatus in which fluid streams of particulate filler and elastomer latex are fed to the mixing zone of a coagulum reactor to form a coagulated mixture in semi-confined flow continuously from the mixing zone through a coagulum zone to a discharge end of the reactor. The particulate filler fluid is fed under high pressure to the mixing zone, such as to form a jet stream to entrain elastomer latex fluid sufficiently energetically to substantially completely coagulate the elastomer with the particulate filler prior to the discharge end without need of adding acid or salt solution or other coagulation step. The coagulated elastomer and particulate filler composite is fed into the aforesaid continuous compounder for processing and control of its moisture level and Mooney Viscosity. Novel elastomer composites are produced. Such novel elastomer composites combine material properties and characteristics, such as choice of filler, elastomer, level of filler loading, moisture level, Mooney Viscosity, balance between molecular weight and amount of bound rubber, and macro-dispersion not previously achieved.

    摘要： A process for the production of a particle composition containing, at least one resin and at least one pigment is described, said process comprising the following steps : •extrusion of a mixture containing said at least one resin and said at least one pigment without induced heating; •subsequent extrusion, with induced heating, of the mixture obtained from the preceding extrusion; •granulation of the mixture thus obtained. With the abovementioned process it is possible to obtain a composition having granules with an average diameter less than 2 microns and a greater homogeneity than the known processes.

    摘要： A process for continuous dewatering/drying of EP(D)M rubber is disclosed. The process comprises continuously charging wet EP(D)M crumb into a single screw extruder having particular structural features and conveying the wet crumb through the length of the extruder under conditions sufficient to expel water, increase the pressure across the die plate of the extruder and heat the crumb. The dried crumb thus extruded is characterized in that it contains less than 1% water. The single screw extruder suitable for the process comprises an inlet or feeding end, an expeller section which contains cage bars, an expander section having a solid shell cover positioned immediately downstream from the expeller section, a die plate and a screw having a constant pitch and a, preferably gradually, decreasing channel depth.
