Abstract: IMPACT-RESISTANT ACRYLONITRILE COPOLYMER PROCESS The process for copolymerization of styrene and acrylonitrile in the presence of a diolefin elastomer in high conversion to polymers having superior impact resistance and other excellent physical properties by the careful control of the percent unrealized total solids during the early stages of the copolymerization is described.

Abstract: The subject invention relates to a process for the selective separation of at least one component of a gaseous feedstream comprising passing the feedstream containing the component through a separation unit, the separation unit containing a porous membrane having a feed side and a permeate side, and a pore size of from about 10Angstroms to about 200Angstroms, and having disposed in the pores of the porous membrane a facilitator liquid comprising a carrier dissolved in a suitable solvent, including: a) dissolving the component in the facilitator liquid on the feed side of the porous membrane at the feed gas/membrane interface; b) forming a component-carrier complex; c) diffusing the complex to the permeate side of the porous membrane; and d) releasing the component from the carrier. The invention further relates to a membrane for the selective separation of at least one component of a gaseous feedstream comprising a porous membrane, having pores of from about 10Angstroms to about 200Angstroms, the pores containing a facilitator liquid having an affinity for the component to be selectively separated, the membrane being capable of operating at a transmembrane pressure of about 100psig to about 300psig. The subject invention also relates to use of the aboveidentified process and membrane for the separation of vapor phase olefins from olefin-containing feed streams.
