摘要:
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.
摘要:
Process for removal of residual styrene monomers from polystyrene and from blends comprising water-insoluble, crosslinked polyvinylpyrrolidone, via treatment with water, which comprises carrying out the treatment on a particulate solid blend.
摘要:
The present invention relates to polymeric products obtainable by mixing (A) polymers which are obtainable by free-radical polymerization of (A-1) ethylenically unsaturated monomers in the presence of (A-2) unsaturated polyalkylene glycols with (B) silicones at a temperature greater than or equal to 30° C. In addition, the invention relates to a process for the preparation of these polymeric products, and to their use in cosmetic preparations, in particular in hair cosmetic preparations.
摘要:
