The invention relates to the use of polymers comprising thermoplastic polymers as filtration aids and/or stabilishing agent for the filtration or stabilisation of aqueous liquids.

Use of polymers comprising thermoplastic polymers as filtration aids and/or stabilising agent

The invention relates to a polyoxymethylene (POM) powder for use in a selective laser sintering process and having the following parameters:  A process for producing the powder, and also moldings produced from this powder by a selective laser sintering process, are also described.

Polyoxymethylene laser sintering powder, process for its production, and moldings produced from this laser sintering powder

Process for production of polymer blends which are suitable as filter aids and are composed of polystyrene and of crosslinked water-insoluble polyvinylpyrrolidones via processing of the two components in an extruder, which comprises melting polystyrene in an extruder and then treating it with the polyvinylpyrrolidone, and adding, to the mixture of the components, from 0.1 to 10% by weight of water, based on the total amount of polystyrene and popcorn polymer, and extruding and comminuting the mixture.
