Abstract: Production of polyisobutene involves polymerization of isobutene (I) using an inert diluent and a Lewis acid (II) containing halogen as catalyst, in which (I) in the form of droplets is contacted with (II) in polymerization equipment. Independent claims are included for (1) polyisobutene with a number average molecular weight Mn in the range of 150000-5000000 g/mole and a dispersity index D in the 4-10 range; (2) polyisobutene obtained by the specified process.

Abstract: Preparation of precipitating polymers comprises spraying polymerization of a monomer solution containing at least an ethylenic unsaturated monomer, at least a solvent, optionally at least a cross-linker and optionally at least an initiator, where the monomer is soluble in the solvent and the obtained polymer through polymerization of the monomers, is insoluble in the solvent. An independent claim is included for a method for thickening aqueous fluids comprising using the polymer.
