    摘要： A process for producing graft polymer particles by bringing into contact with a coagulant a polymer latex (A) obtained by graft-polymerizing one or more monomers including methyl methacrylate with a rubbery polymer, which comprises: a coagulation step in which the polymer latex (A) is injected onto a stirring tank through an immersion nozzle which has an orifice having a sectional area of 40 mm2 or larger and is disposed so as to inject the latex in the same direction as the flow in the stirring tank, at a linear velocity of 50 to 350 mm/s as measured at the outlet of the nozzle to bring the latex into contact with the coagulant and coagulate the graft polymer, thereby obtaining a slurry; and a solidification step in which the resultant slurry is kept at 60 to 100°C to solidify the coagulated graft polymer. By the process, graft polymer particles reduced in the content of fine particles and having a high bulk specific gravity and excellent powder properties can be obtained without the necessity of using an organic solvent or a special apparatus. Thus, polymer particles with excellent powder properties can be stably produced at low cost.

    摘要： A production method of polymer particles produces graft polymer particles by contacting a coagulant with a polymer latex (A) obtained by graft polymerizing a monomer containing methylmethacrylate to a rubber-like polymer. The method comprises a coagulation step in which polymer latex (A) is discharged into a stirring tank from an immersed nozzle provided so that the cross-sectional surface area of the discharge portion is 40 mm 2 or more and the direction of discharge is facing in the same direction as the flow in the stirring tank and so that the linear velocity at the nozzle outlet is a velocity of 50-350 mm/s, and contacted with a coagulant to coagulate the graft polymer and obtain a slurry liquid; and a solidification step in which the resulting slurry liquid is held at a temperature of 60-100°C to solidify the coagulated graft polymer. According to the production method of the present invention, graft polymer particles having superior powder characteristics with few coarse particles and high bulk specific gravity can be obtained without requiring the use of organic solvent or special equipment. Accordingly, polymer particles having superior powder characteristics can be produced in a stable manner and at low cost.

    摘要： A rotor/stator device is proposed having a bearing block, a housing (1), a rotor shaft mounted therein at the housing-side end of which a rotor is fixed that has a conical surface and with which a stator (2) fixed in the housing is concentrically associated, wherein the mutually facing surfaces of the rotor (2) and stator (3) form a gap upstream of which an axial supply connector is connected and downstream of which a radial outlet connector is connected, the rotor and stator being displaceably mounted in an axial manner so as to form a gap whose width can be adjusted, said device being characterised in that, in the region of the supply opening of the rotor/stator device in the supply line just before the rotor/stator device and/or in the housing (1) and/or in the stator (2), one or more outwardly leading holes are provided and, in the annular space about the shear gap next to the outlet opening, at least one further hole is provided. Additionally proposed is a method for the salt-free coagulation of polymer dispersions using the above-described rotor/stator device.

    摘要： A process for the continuous coagulation and drying of rubber latex includes feeding the latex onto an endless conveyor belt (8) which feeds the latex through a coagulator (10). A combination of microwave energy and hot air raises the temperature of the latex causing it to coagulate in a coagulation time of less than five minutes. The coagulated rubber from the coagulator (10) is fed onto a conveyor belt (14) of a stretch unit (12) which stretches the rubber by increasing its speed of travel. The stretched rubber is then conveyed onto the upper belt (18) of a drying unit (16). The drying rubber is passed from the upper belt (18) onto an intermediate belt (20) and then on to a lower belt (22) before leaving the drying unit (16). A combination of microwave energy and hot air in the drying unit (16) is used to dry the rubber to a moisture content of less than 1.5%.

    摘要： Elastomer masterbatch is processed in a continuous compounder (100) having multiple parallel elongate rotors (106) axially oriented in an elongate processing chamber (104). Optionally, additional materials are compounded into the masterbatch, e.g., additives (58, 59), other elastomeric compositions, etc. Preferably, the masterbatch then is further processed in an open mill (120). 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 (57) and elastomer latex (58) are fed to the mixing zone (14, 50) of a coagulum reactor (48) to form a coagulated mixture in semi-confined flow continuously from the mixing zone (50) through a coagulum zone (52) to a discharge end (68) of the reactor. The particulate filler fluid is fed under high pressure to the mixing zone (50), such as to form a jet stream to entrain elastomer latex fluid sufficiently energetically to substantially completely coagulate the elastomer with the particular filler prior to the discharge end (68) without need of adding acid or salt solution or other coagulation step. The coagulated elastomer and particular filler composite is fed into the aforesaid continuous compounder (100) for processing and control of its moisture level and Mooney Viscosity.
