摘要： A humidification system (A) for humidifying a dry hydrocarbon stream includes a column (10) which defines an interior cavity (20). The cavity is partially filled with a bed (12) of a packing material (40) and a layer of water (20), leaving a headspace above the water. An inlet (52) adjacent a lower end of the cavity receives a dry hydrocarbon stream which is broken up by the packing material and dissolves water as it passes therethrough. Entrained water droplets fall out of the wet blend in a disengagement zone (70) above the water layer leaving the hydrocarbon stream humidified yet substantially free of liquid water in an upper region (72) of the column.

摘要： A novel method of preparing carboxyl-terminated polymers. A monomer is mixed with an organolithium initiator in a hydrocarbon solvent so as to anionically polymerize linear living polymer lithium chains. A trialkyl aluminum compound is also mixed so as to form polymer lithium: aluminate complexes in equilibrium with the linear living polymer lithium chains. When a cyclic anhydride terminator is mixed, the cyclic anhydride terminator preferentially reacts with the C—Li center on a living polymer lithium chain rather than with the C—Al—Li center on a polymer lithium: aluminate complex.

The method is particularly useful for copolymerization of anionically polymerizable monomers and free radical polymerizable monomers, and therefore useful for production of PB-g-PS, HIPS, ABS, and MBS etc. Also provided is a reversibly coupled polymer, which, when decoupled, generates “living” free radical for further copolymer chain reaction.

摘要： Diene polymers or copolymers having improved balance between raw polymer viscosity and mixed compound viscosity, useful in tire tread compositions having highly balanced wet traction, rolling resistance, and traction in ice and snow, and fracture properties in the cured and white carbon reinforced states are provided. These diene polymers or copolymers comprise a mixture of diene polymer or copolymer chains containing carbon-tin bonds in the main polymer or copolymer chains and diene polymer or copolymer chains containing terminals derived from hydrocarboxysilane compounds. The diene polymer or copolymers are prepared by first coupling a portion of the living diene polymer or copolymer chains obtained by anionic polymerization using a tin polyhalide coupling agent and then terminating the remaining living diene polymer or copolymer chains using hydrocarboxysilane compounds. The resultant diene polymers or copolymers have improved balance between raw polymer viscosity and mixed compound viscosity when compounded with silica and/or carbon black and cured compositions are useful in tire tread having highly balanced wet traction, rolling resistance, and traction in ice and snow. The polymers can be utilized to form elastomer compositions for tire treads having balanced properties of reduced rolling resistance and wet traction and handling or balanced properties of wet traction and handling and traction in snow and ice.

摘要： Incorporation of neutral water soluble inorganic salts into a precipitated silica improves the filler dispersion in a compounded rubber, reduces rolling resistance (hysteresis), and improves processability. These properties are achieved without loss of the expected reinforcement effect due to the substitution of inorganic salt for SiO2 in the silica. The properties are seen when a variety of silanes and processing aids are added to the silica.

摘要： The present invention provides silica-filled, vulcanized elastomeric compounds comprising an elastomer mixed with at least a silica filler, a processing aid, and a curing agent, and processes for the preparation of the same. Generally, the present invention provides processing aids which effectively reduce or replace the amount (i.e., about 10 percent by weight based upon the silica filler) of the processing aid bis[3-triethyoxysilyl)propyl]tetrasulfide (“Si69”) used in the production of silica-filled rubber stocks. These new processing aids include alkyl alkoxysilanes, fatty acid esters of hydrogenated and non-hydrogenated sugars and the polyoxyethylene derivatives thereof, and combinations thereof, with or without various non-reinforcing fillers such as mineral fillers. The processing aids do not hinder the physical properties of the compounds and have been found to be excellent substitutes for Si69. The processing aids may be supported on the silica filler or any of the other fillers employed in the composition for improved handling, safety and performance. Processes for the preparation of the silica filled vulcanizable elastomers are provided as well as pneumatic tires employing tread stock comprising the novel vulcanizable elastomers.
