Abstract: Disclosed is a process for the preparation of low-peroxide crosslinked vinyllactam polymer by free-radical polymerization in the presence of at least one organic substance acting as antioxidant. The vinyllactam polymer is water-insolubly crosslinked polyvinylpyrrolidone or vinylpyrrolidone copolymer with vinylimidazole, vinylcaprolactam and/or vinyl acetate. The obtained vinyllactam polymer has low peroxide contents, and the peroxide contents do not increase or increase slightly within a certain time and low residual monomer contents. The obtained vinyllactam polymer is suitable to use in the field of pharmaceutical and food applications.

Abstract: The invention relates to a method for producing polymer blends, which are suited for use as filter aids, from polystyrene and cross-linked water-insoluble polyvinyl pyrrolidones by processing both components in an extruder. The invention is characterized in that polystyrene is melted in an extruder, is then mixed with the polyvinyl pyrrolidone, and water is added to the mixture of the components having 0.1 to 10 % by weight with regard to the total amount of polystyrene and popcorn polymer, whereupon the mixture is extruded and comminuted.
