Abstract: 2106375 9217158 PCTABS00016 A process for the production of PVP-H2O2 products in the form of free-flowing powders, or a free-standing, porous solid or foam, is described. To prepare free-flowing powders, a fluidized bed is maintained at a reaction temperature of about room temperature to 60 ·C and is contacted with finely divided droplets of a 30 to 85 % by weigth aqueous H2O2 solution. Preferably the fluidized bed temperature is about 35·-45 ·C, a 5-70 % H2O2 solution is used, and the feed rate of introduction of the H2O2 solution is about 5-50 g/minute/kg PVP present. The PVP-H2O2 product preferably contains about 15-24 %, preferably 18-22 %, H2O2 (1:1 molar ratio) and less than about 5 % water.

Abstract: A composition for preventing or retarding the formation of gas hydrates or for reducing the tendency of gas hydrates to agglomerate, during the transport of a fluid comprising water and a hydrocarbon, through a conduit, comprising, (a) a polymer or copolymer selected from a terpolymer of vinyl pyrrolidone, vinyl caprolactam and an ammonium derivative monomer having from 6 to 12 carbon atoms, selected from the group consisting of dialkyl aminoalkyl methacrylamide, dialkyl dialkenyl ammonium halide and a dialkylamino alkyl acrylate or methacrylate, a copolymer of vinyl pyrrolidone and vinyl caprolactam, and a homopolymer of vinyl caprolactam, and (b) an alcohol containing three to five carbon atoms and one hydroxy group, or a low molecular weight glycol ether containing an alkoxy group having at least 3 carbon atoms.

Abstract: 2083951 9202564 PCTABS00010 What is described herein is a process for making a copolymer of high specific viscosity by polymerisation of maleic anhydride and a C1-C4 alkyl vinyl ether monomer. The invention involves polymerizing said monomers to form a slurry of said copolymer in excess alkyl vinyl ether as solvent and toluene or an aliphatic organic compound as cosolvent, and is characterized by the steps of: (a) precharging a reactor with C1-C4 alkyl vinyl ether as solvent at a reaction temperature, (b) feeding a mixture of maleic anhydride and a C1-C4 alkyl vinyl ether in substantially stoichiometric amounts, preferably with a slight excess of the alkyl vinyl ether, and at a selected rate, into said precharged reactor, and (c) simultaneously feeding a predetermined mixture of toluene or an aliphatic organic compound and a polymerization initiator continuously over substantially the entire period of polymerization.
