摘要: This invention relates to a method of recovering a polymer from an organic mixture comprising polymer and an organic solvent, the method comprising: a) admixing an aqueous solution and the organic mixture by the application of a combined mechanical and hydraulic shear force, the combined mechanical and shear force being sufficient to form a liquid-liquid dispersion; b) removing the organic solvent from the liquid-liquid dispersion thereby forming a remaining solution; and c) separating the polymer from the remaining solution. In one embodiment the polymer is a polycarbonate prepared by the interfacial method, and the organic solvent is methylene chloride.

摘要: Polymer are removed from organic solvent-polymer mixtures by preparing a liquid-liquid dispersion of finely dispersed solvent droplets containing polymer in water, adding this liquid-liquid dispersion to a stirred vessel containing water or other suitable liquid and rapidly evaporating the solvent to produce a slurry of the polymer in a liquid from which the solid polymer particles are recovered.

摘要: Bis(aminoalkyl)siloxane dimers or oligomers are prepared by a process utilizing hydrosilation of an olefinic amine with tetraorganodisiloxane or with bis(dialkylhydrogen)siloxane oligomers to generate high purity bis(aminoalkyl)disiloxane or bis(aminoalkyl)siloxane oligomers at high conversion yield, which may then be subsequently equilibrated to higher molecular weight bis(aminoalkyl)polysiloxanes.
