摘要： Wall temperatures within a movable, internally cooled scraper element that is used to dislodge metal oxide accumulation from the internal wall of a reactor are monitored by a thermocouple electrically connected to mercury baths which are in turn electrically connected to a temperature recorder. The thermocouple output can be used to control a regulator of coolant fed to the scraper element.

摘要： A HOLLOW ELONGATED SHELL HAVING AN INLET AND AN OUTLET AT OPPOSITE ENDS HAS A SERIES OF AGITATING ASSEMBLIES MOUNTED AT AXIALLY-SPACED LOCATIONS IN THE SHELL. EACH AGITATING ASSEMBLY INCLUDES A HOLLOW DRAFT TUBE HAVING INLET PORT MEANS AT ONE END COMMUNICATING WITH THE CORRESPONDING END OF AN ANNULAR FLOW PASSAGE BETWEEN THE DRAFT TUBE AND SHELL AND OUTLET PORT MEANS AT THE OPPOSITE END COMMUNICATING WITH THE OTHER END OF THE PASSAGE. AN IMPELLER IS MOUNTED FOR ROTATION IN THE DRAFT TUBE ADJACENT THE OUTLET PORT MEANS TO FLOW THE PROCESS INGREDIENTS AXIALLY THROUGHT THE DRAFT TUBE AND OUTWARDLY THROUGH THE OUTLET PORTS WHERE THE INGREDIENTS ARE MIXED WITH INGREDIENTS FLOWING INTO THE OTHER END OF THE PASSAGE. BAFFLE MEANS IS ASSOICATED WITH THE OUTLET PORTS TO REDIRECT THE FLOW OF THE REACTED INGREDIENTS AFTER THEY EXIT THE OUTLET PORTS AND TO BREAK UP ANY SWIRL CAUSED BY THE IMPELLER. THE IMPELLER AND BAFFLE MEANS COOPERATE TO PROVIDE HYDRAULIC AND MECHANICAL SHEAR FORCES ON THE INGREDIENTS TO IMPROVE REACTION IN THE APPARATUS.

摘要： The preparation of aqueous latices from solvent dispersions of elastomers and other high polymer compositions has presented problems including excessive viscosity during processing and foaming and coagulation, which have produced losses and increased costs. Herein combinations of steps are disclosed which reduce or eliminate various of these problems; enable the preparation of latices from high solids, high viscosity cements as well as from high solids cements of low molecular weight polymer; enable preparation of latices of grafted or filler extended or filler reinforced elastomers; enable preparation of latices of low molecular weight polymer which are then modified to materially increase the molecular weight of the polymer and/or the latex particle size; and enable the preparation of improved latices both dilute and of high solids contents, which are useful for example for adhesive and film forming purposes. The process in common with that of related copending applications is characterized, inter alia, by the establishment of a flow of latex through the separating zone and the impingement on said flow of the coalesced latex droplets from the solvent vapor stream in which they are delivered to the separator, and in certain embodiments by the use of particular additive materials. New combinations of steps and of apparatus for performing the same are also disclosed and claimed. The process disclosed is applicable to the production of latices from specified rubbery and non-rubbery polymer compositions, and certain of such latices are new and useful products also claimed herein.

摘要： The invention relates to the modification of ethylenically unsaturated polymers using polyfunctional quaternary amidoximidinium salts as the modifying agents. These salts are precursors to the corresponding polyfunctional nitrile N-oxides and the latter, upon being generated from the salt precursors, are the active modifying agents in the modification process. Representative of these salts is terephthalo-bis(hydroximoyl pyridinium chloride).
