    摘要： Apparatus and method for separating a substantially insoluble liquid from a mixture containing a polymer or polymer mixture. The liquid is a vapor at the usual temperature and pressure of the polymer extrusion operation and is kept in liquid form by providing a high pressure region in the extruder. A liquid outlet is provided upstream of the high pressure region and the liquid is maintained under pressure and taken off as a liquid. The pressure-maintaining means may be a liquid outlet provided with a pressure control valve, trap or the like.

    摘要： Production of synthetic vinyl resins having pronounced resistance to color deterioration, while also manifesting high impact strength and transparency, utilizing a butadiene graft polymer formed by the sequential addition to a polymer or copolymer of butadiene of from 80 to 30 parts of monomers for each 100 parts of total resin content, said monomers consisting of from 5 to 80 percent vinyl aromatic compound, from 5 to 50 percent of methyl methacrylate, and from 5 to 60 percent of acrylonitrile, the process being characterized in that at least 80 percent of the butadiene particles at the start are less than 0.1 Mu in diameter and are dispersed in an aqueous emulsion which contains from 0.5 to 10.0 parts of a formaldehyde sulfoxylic salt, and catalytically effective amounts up to three parts of peroxide, for each 100 parts of resinous constituents used, said particle size being maintained at least until polymerization of the monomeric material has been effectively begun, said butadiene graft polymer being independently useful but also being capable of blending with a resin of the vinyl chloride type to produce a final resin of greatly enhanced properties.

    摘要： A LATEX OF A RUBBERY POLYMER HAVING A PARTICLE SIZE OF LESS THAN 0.25 MICRON AND A POLYMERIZABLE VINYLIDENE MONOMER FORMULATION IS SUBJECTED TO POLYMERIZATION CONDITIONS TO PRODUCE POLYMERIZATION AND GRAFTING OF AT LEAST A PORTION OF THE MONOMER FORMULATION ONTO THE RUBBERY POLYMER. SUBSEQUENTLY, A LATEX OF AGGLOMERATED RUBBERY POLYMER HAVING A PARTICLE SIZE OF 0.35-1.2 MICRONS IS ADDED TO THE POLYMERIZING LATEX AND POLYMERIZATION OF THE VINYLIDENE MONOMER FORMULATION IS CONTINUED TO PRODUCE GRAFTING OF AT LEAST A PORTION THEREOF ONTO THE AGGLOMERATED RUBBERY POLYMER.
