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: A process is disclosed for producing filaments from a hydroxy- or aminoalkylmelamine-modified melamine/formaldehyde condensation product. The highly concentrated aqueous solution of a melamine/formaldehyde condensation product is filtered, extruded through a spinning nozzle, the extruded threads are dried in a dry shaft by means of hot air, and the dried threads are processed in a tempering furnace at temperatures that rise progressively up to a maximum temperature from 160 to 250 DEG C, thus hardening the pre-condensed product.
