Abstract: 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.

Abstract: La invencion se relaciona a un metodo para producir mezclas de polimero, que son adecuadas para el uso como auxiliadores de filtro, de poliestireno y polivinilpirrolidonas insolubles en agua reticuladas procesando los componentes en un extrusor. La invencion se caracteriza porque el poliestireno se funde en un extrusor, entonces se mezcla con polivinilpirrolidona, y se agrega agua a la mezcla de los componente que tienen 0.1 a 10% en peso con respecto a la cantidad total de poliestireno y polimero de palomitas de maiz, en donde la mezcla se extruye y pulveriza.

Abstract: A particle composition (I) contains particles of cross-linked polyvinylprrolidone having a particle size distribution in which as greater than 10 wt.% of particles have a particle size of less than 63 mu m, 0.1-30 wt.% of particles have a particle size greater than 1000 mu m and at least 10 wt.% of particles have a particle size of less than 200 mu m. Independent claims are included for: (i) a compact particulate wash and cleaning agent (II) containing 0.5-20 wt.% of the particle composition (I); (ii) a process for the production of the cleaning agent (II) by mixing 0.5-20 wt.% of the particle composition (I) with the other powdered ingredients; (iii) a process for the production of the particle composition (I) by means of popcorn polymerization by polymerization of a reaction mixture comprising N-vinylpyrrolidone and cross-linking agent in the absence of oxygen and polymerization initiators at upto 200 deg C in substance or using water as a precipitation agent and the particle size the popcorn polymer is controlled by introduction of an inert gas stream into the reaction mixture.
