Abstract: A PROCESS IS PROVIDED FOR OBTAINING PARTICULATE HIGH MOLECULAR WEIGHT POLY (VINYL CARBAZOLE) COMPRISING CHARGING (1) MONOMERIC VINYL CARBAZOLE, (2) AN INERT ORGANIC SOLVENT FOR SAID VINYL CARBAZOLE, SAID SOLVENT BEING A NONSOLVENT FOR THE RESULTING POLYMER, AND (3) A CATALYTICALLY EFFECTIVE AMOUNT OF A FREE RADICAL POLYMERIZATION CATALYST TO A POLYMERIZATION ZONE; HEATING THE RESULTING MIXTURE IN SAID ZONE AT A TEMPERATURE RANGING FROM ABOUT 45*C. TO ABOUT 150*C. FOR A PERIOD OF TIME SUFFICIENT TO CAUSE POLYMERIZATION OF SAID MONOMER AND SUBSTANTIALLY SIMULTANEOUS PRECIPITATION FO DISCRETE PARTICLES OF POLY (VINYL CARBAZOLE) FORMING A POLYMER SLURRY, AND THEREAFTER, RECOVERING SAID POLYMER FROM SAID SLURRY.

Abstract: Alkylated polymeric or copolymeric N-vinyl lactams are obtained by heating one mole of a polymeric or copolymeric N-vinyl lactam with 0.05 to 12 moles of an a -olefin containing at least 2 carbon atoms or with 0.05 to 12 moles of a halo-a -olefin containing 2 carbon atoms, the halo-a -olefin being a chloro-fluoro-a -olefin or a fluoro-a -olefin, in a solution of an organic solvent common to the said polymeric or copolymeric lactam and the said a -olefin or halo-a -olefin in the presence of 0.025 to 0.30 mole of an organic peroxide catalyst per mole of the said a -olefin or halo-a -olefin at a temperature ranging from 80 DEG to 200 DEG C. A long list of suitable comonomers is given, those exemplified are vinyl acetate and ethyl acrylate. The a -olefins may have molecular weights ranging from 28 to 2500.

Abstract: A PROCESS IS PROVIDED FOR OBTAINING PARTICULATE LOW MOLECULAR WEIGHT POLY (VINYL CARBAZOLE) COMPRISING CHARGING (1) MONOMERIC VINYL CARBAZOLE, (2) AN INERT ORGANIC SOLVENT FOR SAID VINYL CARBAZOLE, SAID SOLVENT BEING A NONSOLVENT FOR THE RESULTING POLYMER AND (3) A CATALYTICALLY EFFECTIVE AMOUNT OF A CATIONIC POLYMERIZATION CATALYST TO A POLYMERIZATION ZONE; MAINTAINING THE RESULTING MIXTURE IN SAID ZONE AT A TEMPERATURE RANGING FROM ABOUT -50$C. TO ABOUT + 100$C. FOR A PERIOD OF TIME SUFFICIENT TO CAUSE POLYMERIZATION OF SAID MONOMER AND SUBSTANTIALLY SIMULTANEOUS PRECIPITATION OF DISCRETE PARTICLES OF POLY (VINYL CARBAZOLE) FORMING A POLYMER SLURRY, AND THEREAFTER RECOVERING SAID POLYMER FROM SAID SLURRY.

Abstract: Process for the preparation of 1,3-bis(2-pyrrolidonyl butane is provided comprising heating 1,3-bis(2-pyrrolidonyl)-1-butene to a temperature above the melting point thereof under hydrogen pressure in the presence of a hydrogenation catalyst for a sufficient period of time to substantially hydrogenate the 1,3bis(2-pyrrolidonyl)-1-butene and thereafter, recovering the hydrogenated product. Process is also provided for separating aromatic hydrocarbons from mixtures of aromatic/non-aromatic hydrocarbons comprising contacting a mixture of aromatic/non-aromatic hydrocarbons with 1,3-bis(2-pyrrolidonyl)butane to form an aromatic hydrocarbonrich extract phase and a raffinate phase, separating the aromatic hydrocarbon-rich extract phase from the mixture, and recovering the aromatic hydrocarbon from said extract phase.
