IPC: C08F6/10
Filed: 1990-08-30
Abstract: A polymerization process wherein monomers are polymerized in liquid diluent to produce a liquid slurry containing particles of normally solid polymers, periodically opening a product takeoff port to allow a charge of liquid slurry to flow into an elongated confined zone including a flash line heater and then into a flash chamber wherein the lighter components are separated from the polymer The process is particularly characterized by the fact the elongated confined zone is constructed such that the flow time of the charge of slurry in the flash line heater is equal to at least about 25 percent of the time between the time of the closing of the settling valve and the next opening of the settling valve.

Abstract: A silicone cyclic, such as hexaorganotrisiloxane is lithiated with an alkyl lithium compound followed by treatment with a diorganohalosilane to produce a polydiorganosiloxan having a terminal diorganohydridesiloxy unit. The platinum catalyzed addition of a 2-alkenyl-6-organophenol results in the production of a phenol-siloxane macromer. Conversion of the phenol-siloxane macromer to a silicone polyphenylene ether graft copolymer is effected by oxidatively coupling the 2,6-diorganophenol to the phenol-siloxane macromer.

Abstract: A tau-dither code correlation tracker includes a code clock (12) and phase shifter (13) for clocking the local code. A sequency of tau-dither patterns (32-35) are applied to the phase shifter (13) wherein each pattern has an incrementally displaced average phase shift with respect to an adjacent pattern in the sequence. The incremental average phase shift displace­ments are smaller than the phase shift increments provided by the code clock for enhanced resolution. The correlator output is amplitude detected and applied directly and through a polarity inverter to an electronic switch (16). The electronic switch (16) is controlled switchably to apply the direct and polarity inverted amplitude signal to an integrator (21) in accordance with the tau-dither pattern. The integrator output is compared (22) to a threshold to control the sequency of tau-dither patterns.

Abstract: A method for determining the concentration of carbon monoxide, carbon dioxide and hydrocarbons in motor vehicle exhaust gases, comprises establishing a flow of the gas, filtering and directing the gas to a container (10) having an outlet to atmosphere, establishing a flow of a purging gas and alternately directing the purging gas and a portion of the exhaust gas withdrawn from the container (10) through a non-dispersive infra-red analysis cell (15,100-107) having a thin wall construction and wherein the gas is analysed by conventional methods, the cell being recalibrated during purging. The purge gas and exhaust gas are alternately directed through the cell (15, 100-107) by a solenoid valve (12) controlling the connection (14) of the cell to the purge gas or container (10) and the operation of a pump (11) located on the gas outlet side of the cell which draws the purge gas through the cell at a higher rate than the gas to be analysed. 
     The method provides for rapid warm-up of the cell and for reduced rate of contamination of the cell by the exhaust gases.

Abstract: Synthetic elastomers are typically made commercially by employing emulsion polymerization or solution polymerization techniques. In such solution polymerization techniques, it is desirable to operate at the highest solids content which is practical. As a general rule, it is not practical to prepare such rubbers by solution polymerization at solids contents of higher than about 20 percent. However, the subject invention reveals a technique for preparing such rubbers by high solids solution polymerization at extremely high solids contents. This technique offers substantial advantages associated with eliminating large quantities of organic solvents. The subject invention more specifically relates to a process for the synthesis of polydiene rubber by continuous high solids polymerization which comprises: (1) continuously charging at least one diene monomer, at least one organolithium compound, and from about 4 to about 50 phm of at least one organic solvent into a reaction zone; (2) allowing the monomers to polymerize to a conversion of at least about 90% while utilizing conditions under which there is sufficient evaporative cooling in said reaction zone to maintain a temperature within the range of about 10°C to about 150°C; and (3) continuously withdrawing said polydiene rubber from the reaction zone.
