Abstract: In the production of dispersions by spraying a solution containing polyarylene-ether-sulfone (I) into an agitated coagulation bath, the solution contains 0.5-5 wt.% (I) and the average particle size (d50) of the primary particles in the dispersion is up to 100 nm. Independent claims are also included for: (a) Dispersions produced in this way; (b) coatings produced from the dispersions; (c) the coating process; and (d) coated household articles.

Abstract: Filaments with a relative viscosity RV of 2.0 to 3.0 (measured at a concentration of 1 g of fibres per 100 ml in a 96 wt % sulphuric acid, based on polycaprolactam, obtainable by:(a) extruding a melt consisting essentially of caprolactam through a spinning nozzle to form caprolactam filaments;(b) cooling the filaments thus produced and (c) drawing the cooled filaments off at a rate of at least ¢3600 + 1250.(3.0-RV)!m/min, the polycaprolactam used being produced in the presence of at least one bicarboxylic acid from the group: C4-C10-alkane bicarboxylic acids, C5-C8-cycloalkane bicarboxylic acids, benzole and naphthaline bicarboxylic acids which may have up to two sulphonic acid groups and whose carboxylic acid groups are not adjacent, N-C1-C6-alkyl-N,N-di(C4-C10-alkane carboxylic acid)amine, 1,4-piperazine-di(C1-C10-alkane carboxylic acid), and a process for producing these filaments, their use for the production of fibers and flat products, and fibers and flat products made of these filaments.
